what is the similar characteristic among whale and crocodile..plzz.
Answers
Hello friends.
We still don’t know why a raven is like a writing desk, but, according to anatomist Matthew McCurry and colleagues, we know a bit about why a crocodile is like a whale.
Today’s crocodylians and toothed whales aren’t closely related at all. They last shared a common ancestor over 288 million years ago, when the forebears of reptiles and mammals parted evolutionary ways. Despite this, though, both the reptiles and mammals have jaws lined with conical teeth and a similar array of snout shapes. Despite vastly different evolutionary histories, the two groups have come to resemble each other.
This phenomenon is called convergence, and it pops up all over the tree of life. The similarity of a pterosaur’s wing to that of a bat’s, the shared, streamlined shapes of sharks and ichthyosaurs, and the repeated evolution of saberteeth in fossil mammals are all examples. The physical constraints of certain activities like flying, swimming, and biting will nudge distantly-related species to evolve into similar form.
