I think that the correct answer is theory two, because a mutation will only stick around if it has a reason to (ex, it's beneficial)., therefore a giraffe would not pass on a longer neck repeatedly unless necessary.

# data[].attributes.body
i think theory two if correct because there would be more deaths with short necked babies so when they grow older eventually there would only be long necked giraffes left so when they breed, there would be dominant long neck genes

I think that long necks was a mutation and then their offspring inhited it and it became a common trait to giraffes.

# data[].attributes.body
I believe that Theory 2 is more accurate because mutations are random, and acquired traits cannot be passed down. The food source of giraffes are leaves in high trees, so it would make sense for the giraffes that were able to reach the source would be able to survive longer and reproduce, as opposed to the giraffes that cannot reach the food.

# data[].attributes.body
theory 2 explains why giraffes have long necks because in number 1 that’s showing an acquired trait but in number 2 it shows that the giraffe with a smaller neck dies off because it can’t reach but the giraffes with the longer neck trait survive.

# data[].attributes.body
I think its theory 2 beacuse would their neck just be stuck streched

Btw heres a giraffe with no neck

# data[].attributes.body
I think its theory 2 because the flaw in theory 1 is that it is saying that you can pass on an acquired trait which you cannot do because it is not in your genes. this proves its theory 2 along with the fact that it just makes more sense.

# data[].attributes.body
cuz the trait that was more desirable was passed on

# data[].attributes.body
I think this because you can't pass on an acquired trait which is what #1 is saying. In #2 it says that its a gamble whether you get long or short necks. When the short neck Giraffes die faster, the long neck giraffes end up living longer so that reproduce to more likely make more giraffes long neck.

i say yes to theory 1 because it allow them to reach food and nutrients that others cannot.

# data[].attributes.body
as trees grew taller to avoid giraffes, giraffes needed taller necks to get enough food to survive and reproduce, so giraffes with taller necks were more likely to pass on their neck length to the next generation of giraffes

# data[].attributes.body
I think it would be theory 2 because theory 1 is just an acquired trait. So it wouldn't pass on. Theory 2 talks about DNA and passing on DNA and people who didn't have long necks died off, so over time, giraffes grew long necks.

I think theory 1 is correct because they probably did need long necks to get food from the trees.

I think theory 1 is correct because they probably did need long necks to get food from the trees.

because giraffes can get food if they have tall necks so the short necked giraffes would be malnourished and die/not reproduce as much.

# data[].attributes.body
i think that theory 2 makes more sense because if the trees are tall, giraffes with long necks are more likely to survive because they can reach the food. and then the other would die off and the long neck trait would get passed down. and also stretching necks is an aquired trait and you can't pass that down

to reach higher food sources, their descendants inherited longer, stretched-out necks. Traits acquired in an organism's lifetime were transmitted to the next generation.

I think that theory 2 make more sense because if they stretched their neck they can't pass it onto the next generation, so some giraffes probably did have longer necks than other giraffes and the giraffes that didnt have long neck could not eat so they ended up dying so it cant pass on the short neck dna.

# data[].attributes.body
I think Theory 2 is true because the giraffes with short necks can't reach the food so they die before they have kids

# data[].attributes.body
I believe theory 2 is true because it makes more sense also because the trees that they eat from are tall so it could be that the short ones died because they cant get any food.

# data[].attributes.body
I think that theory 2 is right.

Giraffes have long necks for a reason if a giraffe has a short neck for it's whole life, then it would have a hard time trying to reach food and ect.

# data[].attributes.body
i think theory 2 is correct because it gives a explanation of what evolution is. the taller ones will survive because they can reach high places which is where there food is.

Theroy.2. The giraffes with long neck could reach the tall trees but the giraffes with short necks can't. And this might lead to giraffes with short necks not getting food and the nutrients they need. Causing them to die and not pass on  there genes. Which makes sense because if the short necked giraffes were to pass on  there genes for short necks the next generation would not survive because they would not be able to reach the tall trees.

I think that Theory one is correct because the trees they eat from are tall so it probably would stretch them out and over time that would just become a trait

# data[].attributes.body
I think the Giraffes got a long neck mutation then it got passed on. I say this because benefitial mutations stay and I think over time the long necks proved to be more beneficial and the long neck Giraffes survived and the short neck ones died.

# data[].attributes.body
I think theory 2 is correct because they wouldn't be able to just randomly stretch one day and pass it on. Also, it would be harder for them to survive with shorter necks because they couldn't reach things as well so it makes sense why they would starve with short necks. And then the ones with the long necks survive and pass on their genes to their offspring.

# data[].attributes.body
i think theory 2 is correct because the taller giraffes got more food to survive than the shorter one due to height. so the taller giraffe had a higher chance of survival, and so eventually the shorter giraffes went extinct because they got less food than the taller ones.

# data[].attributes.headline
i think theory 1 is right because it does make alot of sense to me for them to just strech their necks to try and reach taller places and over time they get longer necks (if this makes sense to you in a way?)

i think theory 2 makes the most sense because with longer necks, they are able to reach higher trees and get better food. the giraffes that dont have long enough necks didnt get enough food and died off. the longer necked giraffes reproduced leading the long neck giraffes to overtake the shorter ones.

# data[].attributes.headline
i Believe it is this one since it seems more believable than giraffes stretching their necks, since the ones with naturally long necks were probably the ones who were able to eat, so the ones who didn't have long necks couldn't quite eat enough and they died off

I think that theory 2 is correct because giraffes with short necks would die off if they can't reach the high tree leaves, while giraffes with longs necks would be more successful and have offspring that also have that trait.

# data[].attributes.body
I think theory 1 is correct because if they stretch it every generation, after a lot of generation it would be very long instead of extinct the "short" neck ones

# data[].attributes.body
I think theory 2 is correct because of mutations. There was probably a mutation that made the giraffes necks longer. Then, since it was useful for their environment, that mutation was passed on. This happened many times over many generations and now giraffes have long necks.

# data[].attributes.body
This theory is most likely because it makes the most sense, and would explain why we don't see short necked giraffes today. The stretched neck trait would also be an acquired trait, so it would not be passed down along generation.

# data[].attributes.body
I think its theory 2 because Darwin's theory said the fittest survive.

# data[].attributes.body
I think theory 2 is more likely for why giraffes got their long necks. The giraffes with shorter necks were dying because they couldn't access the food/resources (leaves) they needed to survive. Because of this more giraffes developed longer necks.

# data[].attributes.body
I believe theory two is correct because of the rules of inherited traits and Darwin's theory of evolution. His theory states that those of a species that are better genetically equipped to live and survive in their environment will be able to live long and healthily enough to pass on their traits to their offspring therefore continuing their specific genetic code. This means that those who didn't have long necks to reach food would not be alive or healthy enough to pass off their short necked traits to their children.

# data[].attributes.body
I think theory 2 is correct because the trees they eat is tall and they had to adapt to there environment giving them long necks

# data[].attributes.body
I think theory 2 is correct because the giraffes that have long necks will be able to survive and also be able to pass that trait on. On the other note the giraffes with the shorter necks will not be able to survive nor pass their traits to their offspring.

# data[].attributes.body
I think that theory 2 makes more sense because longer necks give a bigger advantage for Giraffes like reaching food higher up. The ones with short necks don't have a chance with longer necked giraffes.

# data[].attributes.body
I think that theory 2 is correct because of natural selection and the fact that animals cannot choose when to adapt, it just happens.

# data[].attributes.body
I think theory 2 is correct, because the giraffes with longer necks were able to access more food. The shorter necks couldn't get food and died.

# data[].attributes.body
I think theory 1 is correct because it makes sense that over time they're neck would get longer if they wanted to make the neck longer, it would then get passed on.

# data[].attributes.body
i think girrafes have long necks because they need to get there food from tall trees and w/o there long necks they probs would uh idk

# data[].attributes.body
i think its thery 2 becasue the ones who were short would have less food so they would preproduce less.

# data[].attributes.body
I think theory 2 is correct because since giraffes get their food from tall trees, it makes sense that the taller giraffes would survive.

# data[].attributes.body
I think theory 1 is correct because over time what they needed adapted to them and changed over time.

# data[].attributes.body
I think theory one because it makes more sense that over generations their necks had just gradually grown longer and through generations they evolved to naturally have long necks.

# data[].attributes.body
eh this seems like it would be right, the giraffes with long necks could survive better because they could reach more food.

# data[].attributes.body
i think theory 2 is correct because the trees they eat from are tall so that means short giraffes would not be able to get as much food which is natural selection

# data[].attributes.body
I think theory 2 is correct because the reason giraffes have long necks is to reach food, and they got this trait because the ones that had short necks couldn't reach food and died.

# data[].attributes.body
I think that theory two is correct because the giraffes that couldnt reach tall trees would not survive and the necks would get longer

# data[].attributes.body
I think theory 2 is the most likely to be right because shorter necks would not be able to get food.

# data[].attributes.body
I Think theory 1 is correct because it makes sense that the necks used to be short, so they constantly had to stretch necks to get food. this means they would have adapted, causing the species necks to grow.

# data[].attributes.body
correct because they stretch to get food

# data[].attributes.body
I think that theory 2 is correct because animals can't just stretch their body and evolve to be like that. theory 2 says that the giraffes with the shorter necks could not get food so the giraffes evolved to have longer necks to get food

# data[].attributes.body
I think theory 1 is correct because shorter necked giraffe ancestors continually stretched and strained their necks to reach higher food sources and their descendants inherited longer, stretched-out necks.

# data[].attributes.body
I think theory 1 is correct because their necks stretched and adapted to tall trees to survive

# data[].attributes.body
i think theory 2 is more likely because giraffes need long necks to eat and survive. if they don't have long necks they cant reach food and they will die. theory 1 does not makes sense because stretching out your neck is an acquired trait and you are not able to pass on acquired traits.

# data[].attributes.body
I think theory 2 is correct because giraffes with longer necks would be able to live longer.

# data[].attributes.body
I think theory 2 is correct because giraffes need long necks to eat from the trees. Giraffes with long neck genes live long enough and reproduce, sharing those genes. Giraffes with short necks don't live long enough to reproduce since they can't get food.

# data[].attributes.body
Theory 2 must be correct because theory one is wrong. theory one says that you can pass on acquired traits to offspring, and that's not true. The middle school lessons need a correct answer to work.

# data[].attributes.body
I think theory 2 is correct because if you stretch your neck during your life thats an acquired trait and you cant pass them to offspring

# data[].attributes.body
Theory 2 is correct because short giraffes wouldn't be able to reach their food which could make the starve and die. But then tall ones would be able to reach their food and survive. Also I don't think bones can stretch.

It would make more sense for theory 2 to be true because if an giraffe stretched it's neck out over the course of it's lifetime, the stretched neck would be an acquired trait and would not be passed on. However, if certain giraffes were taller than the others and could reach the trees while others couldn't, they would survive and be more likely to pass on genes to their offspring.

# data[].attributes.headline
I think theory 2 is correct because generation by generation, longer necks survived more longer, because they were able to get food more easier than short necks. Which increased the population of long necks.

I think its theory 2 because if the giraffes need to eat from super tall trees, the ones with shorter necks would die off. That would mean that the taller giraffes would have more babies and effectively remove the short necked giraffes from the population.

# data[].attributes.body
I think theory 2 is correct because it would be easier for taller giraffes to reach the food, so they could stay alive longer and have more babies. I also think this because it takes a lot more than just stretching to change the shape of a body part.

I think theory 2 because i think the ones with short necks would most likely die of starvation since they wont be able to reach like trees.

i think that theory 2 makes more sense than theory 1 because the longer necked giraffes reproduced more and they became the more superior breed

I think theory 2 is correct because they most likely evolved to keep themselves safe.

i think theory 2 is correct because because the giraffes with long necks will be able to eat and reproduce with other long neck giraffes making longer neck giraffes.

# data[].attributes.body
i think theory 2 is correct because you cant just stretch your neck and if you could it wouldn't get passed down and would just be a acquired trait

Because the short ones die out cause they can't eat from the trees.

# data[].attributes.body
I think that theory #2 is right. Theory #2 is explaining exactly what evolution is. The taller ones will be more likely to survive because they can reach the trees better. The ones with shorter necks will have a harder time surviving. Theory #1 is wrong because if you stretch your neck it doesn't become longer. That just doesn't make sense.

# data[].attributes.body
I think this because they needed long necks to eat so then the short necked ones died out, because they couldn't eat.

# data[].attributes.body
I think theory 2 is correct because it would show Natural Selection in process. The longer necked Giraffes would be able to get food while shorter necked giraffes wouldn't be able to get food and die off.

i think it is theory 2 because. they cant pass down something the acquired in life.
