bear to whale?

Question

has anybody heard the theory that whales evolved from massive beras? and is it true I know it sounds like a stupid thing to say if u havent researched it but it could actually be true, I think that scientists have found bones in the fins that are similar to bear's paws!

Answer 1

It's not stupid.

Darwin himself once witnessed a bear swimming around in a lake with its mouth open, eating all sorts of insects that were on the surface, 'rather like a whale' he remarked to himself.

The bones inside a whale's fin aren't like bears particularly. They're like the hand bones of any mammal, whale, bat, lizard, bear, human - the same fingers, the same wrist...

Though whales didn't evolve from bears they did come from land living animals.

Answer 2

There isn't any theory that bears evolved from whales.

As Leviathan noted above, it was Darwin who witnessed a bear swimming around a lake with its mouth open, and hypothesised that one could imagine the descendants of this creature becoming "almost like a whale". He didn't think whales actually evolved from bears.

In fact, we have pretty good fossil evidence now that whales actually evolved from small wolf-like creatures (not related to wolves, though - their closest living relative is the hippo).

We actually have a whole series of transitional fossils linking whales to land animals - including one called Ambulocetus, "walking whale", which is clearly a whale with legs. Something to show the next creationist who claims there are no transitional fossils.

Answer 3

I think it would be the other way around. The evidence of similar bones suggests homologous structures meaning they probably shared a common ancestor somewhere, sometime.

Answer 4

Any "data" of this happening is in trouble-free terms speculative. no person grew to become into there to witness a undergo with "truly whale like" attributes that helped it proceed to exist greater advantageous than different bears, nor will we see any bears immediately that are in the technique of adjusting into greater whale-like. i assume that would desire to have been a one time adventure and the 1st bears that have been given those first whale-like beneficial factors might desire to have been fortunate adequate to proceed randomly coming up further and extra whale-like beneficial factors, whilst the unfavorable bears we nonetheless see as bears immediately weren't fortunate adequate to have stepped forward any of those whale-like beneficial factors that would desire to have helped them proceed to exist. probably because of the fact they weren't compelled by skill of their environment into the sea to seek for nutrition. How fortunate for people who have been that they thankfully had some random mutations that grew to become them into whales over hundreds of thousands of years! whats up, i assume i will make up those fish memories besides as everyone. perhaps I might desire to grow to be a "scientist" and placed up a paper. as long as you're saying it grew to become into evolution in action, they are going to print noticeably much something in the technological expertise journals at the instant.

Answer 5

I don't know about bears...

In the early part of the foetus's life, it has tiny back legs, which disappear long before it is born, suggesting it is decended from a land mammal

Answer 6

No it doesnt work that way. They would both have evolved from a common ancestor.

Answer 7

i heard that they evolved from aquatic bear-like prehistoric creatures
