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.

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

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. ]]> 2018-03-29 13:45:37 UTC https://padlet.com/bnsnyder/ej1dkphxalwi/wish/247249490 https://padlet.com/bnsnyder/ej1dkphxalwi/wish/247249548 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

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 ]]> 2018-03-29 13:45:53 UTC https://padlet.com/bnsnyder/ej1dkphxalwi/wish/247249601 https://padlet.com/bnsnyder/ej1dkphxalwi/wish/247249921 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.

2) Water used to be where our dessert is now

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.

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
