What class of aquatic creatures evolved from artiodactyla?
Whales and dolphins are believed to have evolved from artiodactyls. This is supported by genetic and anatomical evidence, showing a close evolutionary relationship between these groups.
Why are vestigial structures considered critical evidence of evolution?
Vestigial structures are considered evidence, but no more critical than any other line of evidence in Biology and palaeontology. They're considered evidence, not because of their function, but because of the way their morphologies follow the nested hierarchies of biology: the vestigial legs of whales, for instance, have exactly the kind of shape we would have expected them to have if whales had descended from land mammals. The same goes for human tailbones and embryonic branchial ridges, the wings of emus, and so on.
What is the evolutionary relationship between the fin of a fish and the flipper of a whale?
There is no actual evolutionary link between whales and fish. Whales are mammals and looking at the structure of a whales flipper it looks a lot like a hand. Fish however have no bone structure in their fins.Second Answer:They're an example of convergent evolution - two structures with common features which have evolved like that due to a similar/the same purpose despite having unrelated origins. Flippers have hidden fingers.
Why do whales have pelvic bones and fish don't?
Whales are mammals ; see relevant link for additional information . Whales have pelvic bones because millions of years ago, they were land animals, but as they evolved, they no longer needed their pelvis because over time they lost their need for legs. So now their pelvis and legs are vestigial, meaning they no longer serve their original purpose. They just kept the trait. As for fish, they never had legs, so no need for a pelvis.
Do whales eat crabs?
no
How does fossil evidence from the ancestors of whales support evolution?
hard core
What part of a whale is evidence for evolution?
The evidence for evolution in whales can be seen in their skeletal structure, particularly in the remnants of hind leg bones found within the body. These vestigial bones indicate a shared evolutionary history with land-dwelling mammals and suggest that whales evolved from terrestrial ancestors.
What class of aquatic creatures evolved from artiodactyla?
Whales and dolphins are believed to have evolved from artiodactyls. This is supported by genetic and anatomical evidence, showing a close evolutionary relationship between these groups.
Do killer whales use clicker?
No, there is actually evidence for killer whales speaking english.
Where whales never land animals?
According to evolutionary theory whlaes are descended from land animals, though these land animals probably looked quite different than whales do.
What evidence about the ancestors of whales do fossils provide?
You can see that Whales have hipbones, because they use to be mammals, that walked on 4 legs.
What evidence do fossils provide about ancestors of whales?
You can see that Whales have hipbones, because they use to be mammals, that walked on 4 legs.
What evidence supports the hypothesis that whales were land dwelling mammals?
they had hip bones
What difference did scientists discover between today's whales and fossils of their ancestors and how does this show whales and animals with four legs probably descended from a common ancestor?
Scientists have discovered that whales' ancestors had vestigial hind limbs, now absent in modern whales. These vestiges are important evidence of a shared ancestry with four-legged land animals. The presence of these anatomical remnants suggests an evolutionary link between modern whales and four-legged animals from a common ancestor.
What evidence supports the hypothesis that whales evolved from land-dwlling mammals?
Theory of evolution
What evidence supports the hypothesis that whales evolved from land-dwelling mammals?
The evidence that supports the hypothesis that whales evolved from land-dwelling mammals includes the sinonyx. This is a wolf sized mammal that is believed to be a transition between the land animal and the ocean whale.
What evidence is there to suggest the existence of whale footprints in the ocean?
There is evidence of whale footprints in the ocean in the form of acoustic recordings that show unique patterns created by whales moving through the water. These patterns are similar to footprints left on land and suggest the presence of whales in the area.
