2. animals lived over 200 million years ago.
3. People found the very first tetrapod in the world.
4. Some animals had different features like fish with fingers.
5.Animals started to grow hands and legs and it might be some genetic variation.

1) desert was covered in water
2) first found on earth
3)

# data[].attributes.body
1.Whales used to have legs
2.The sahara desert used to be partially underwater
3.A wold had a bump on its head that was related to a Whale.
4.How does the evolution correlate to the way animals move?
5.

# data[].attributes.body
1. The Cambrian Explosion was about the mammals that were in and lived the ocean and occurred as a evolution towards land and later on it will fossilize
2. Because whales were able to evolve to land animals overtime to create a new species
3. Mammals relate towards whales because the bones were similar towards the whale's bones as a mutation.
4. A Tetrapod is a mammal that is part land and sea that is like a lizard (not really) and it was significant towards whales because they were capable of having the same and similar traits towards whales

1. A walnut shaped bump was on the skeleton of what seemed to be a carnivorous mammal.
2. The desert was once covered in water but dried up
3. There is some uncertainty as to why whales are so different from the rest of the mammals
4. Whales once had 4 limbs but adapted to swimming in the ocean
5. Mammals do not swim like fish

# data[].attributes.body
1. There was whale skeletons found in the desert because it was once an ocean.
2. Mammals were first found on earth.
3. Mammals can breathe air and they are warm-blooded.
4. Mammals on land have evolved.
5. Whales have evolved from land animals.

1.when animals get fossilized.
2. There was once water in the dessert but it all dried up and so all the whales died and their skeletons remained.
3. Mammals are warm blooded, they breath air, most evolve on land.
4. The skull was thought to be a wolf but they later discovered that it had a bump on the back only of a whale.
5. it use to be underwater.
6.Fish swim by flexing their fins side to side and the marine mammals use theirs to go up and down.

1. When a radiation explosion happened and fossilized the animals
2. The dessert was once an ocean.
3. They are to be know to evolve on land
4. warm blooded animal that is distinguished by fur or hair.
5.The bump was related to a whale.

# data[].attributes.body
1. Mammals appeared on earth over 200 million years ago.
2. Whales are one of the few mammals that have a complex brain like we do.
3. 1978 skull - walnut sized bump on the underneath and it was part of the animals ear
4. Whales were once believed to be 4 legged animals.
5. Otters swim like whales, moving their spines up and down.

# data[].attributes.body
1) How everything on earth came to be and evolved
2) Water used to be where our dessert is now
3) They are mammals and they have the same type of brain/thought process as we do
4) Dolphins and whales swim by moving their spines like how land animals run.
5) The fish that come out of water to land became reptiles.

# data[].attributes.body
1. Sudden appearance of fossil records of complex organisms.
2.The desserts was once filled with water and whales and fish and sea mammals used to be there.
3. Because mammals evolved on land and dolphins and whales evolved from land mammals.
4. A tetrapod is an animal that is an aquatic and can go on land and this started evolution because we had to get on land to evolve from fish. all the animals that lived, lived in the sea.
5 mammals are animals that are warm blooded vertebrae and they can have fur too.

1.Mammals all beath air and give birth to young
2 All mammals evolved on land but dolphins and whales are a mystery
3 they found a skull that looked like a woof but had a whale skull peacie
4 they think that whales were once on land and now in water
5 the dessert was once underwater but now is land and they'er is whale skeletons all over in one part of the desert

# data[].attributes.body
2) there was  water covering the desert.
video) whales are in their own groups that can't be compared to anything else.
3) there was a bump on the skull that resembled a wolf.
6) marine mammals breath 02 from the air while the fish get it through the water
5) mammals are air breathing, that breed sexually but don't lay eggs.

# data[].attributes.body
1. mammals were discovered over 200 million years ago
2. there was water covering the desert at one point and when the water dried up the whales died because they had no water to survive
3.the becalisouras whale had something that the whales now a days don't have
4. whale are believed to once be 4 legged animals
5.over the years whales evolved from being a land animal to being a water animal

# data[].attributes.body
1. whale fossils where  found in the desert because a lot desert where still under water.
2. mammals are breath air and give  birth to live young  also they are warm blooded
3.  they would find marine fossils in pa because it covered mostly with water
4. marine mammals breath air and give birth to live young. then fish the breath oxygen from water and give birth gelle eggs
5.  land mammals and aquatic they all use there spins the same way.

# data[].attributes.body
1. Mammals first appeared on the Earth 250 million years ago on land.
2. Whales and Dolphins are mammals too, so they had to evolve on land first.
3.Whales are one of the few species that have complex brains similar to humans.
4. Whale Skeletons were found in the Saharan Desert, which used to be a sea.
5. Whales once had 4 limbs, but adapted to swimming in the ocean.
