1. What do you think could explain the differences in the stickleback population in the fossil lake over the 20,000 years shown?

2. What questions do you have about the sticklebacks or about how changes in populations happen over time?

I think the reason they have that is because over time they found new things to eat and started to grow and when they had babies it would pass to them.

are they able to grow a new bone?

1. I think the fishes started to have a pelvic because over time their bodies change and they probably start to grow.

2.are they still around the world ?

1.I think the reason they have evolved over time is because they have had to adapt to new climates and new territories where they need certain abilities or protection.

2.How did they grow new bones?Like over time did they just randomly start growing.

I think the Reason they had a Pelvic bone was to adapt to their environment or it was just a natural evolution.

2. Can they regenerate bones?

Evolution is strongly a process of genetic change over time, and the genetics of... those that occur within the populations of the species

1. I think it depended on what they ate or their different enviroments they got used to living in.

2.Why are they called sticklebacks?

1. I think the reason why they change over the 200 century is because of environment pressure and climate changes

2. Do they change if environment pressure reduces?

1.This leads us to understand evolution as a process of changes at the species level, different from those that occur in each individual organism.

1. I think the reason is because they changed throughout the time past.

2. How do they change?

1.I think that when they go to a new area and their body starts adjusting to the new living space and they start growing new body parts to survive.

2.Are the sticlebacks still alive.

1. The difference in the stickleback population in the fossil lake 20,000 years shown is that over time, there various of new life that help stickleback survive over these year and change it's growth.
2. Were the Stickleback hostile?

1. I think the reason they change it is because of the environment and climate.
2. how do they change

1. I think the reason for them to have different Pelvic bones might be because they could have come from different places.

2. who was the person who discovered the Stickleback Fish.

because they change over time

1. I think that the reason some stickleback have pelvic bones and others don't is because they had to learn to adapt to new habitats. Sticklebacks possibly earned their bones from other sea animals as they spent time at the sea. They possibly need these bones for protection or to catch food.
2. What do stickleback eat?
What eats a stickleback?

1. the difference that fish from 20,000 years ago has is that since it has been around for a long time, it is getting older and that is why its body has changed.

2 . How do their body changes

1. I think that as they are born other fish change their bones each fish changes maybe they are the same but each fish is born with different bones

2. how do changes occur over time

1. I think that the bones of the fish are different because some of them are born with their babies

can they regenerate bones..?
