The stegosaurian forelimb has evidence for a sauropod−like metacarpal configuration [11] This was a different evolutionary strategy than megafaunal mammals such as modern elephants. Therapsids started evolving diverse and specialized forelimbs 270 million years ago, during the Permian.
Diagram of the digestive system of a cat The digestion system of cats begins with their sharp teeth and abrasive tongue papillae, which help them tear meat, which is most, if not all, of their diet. Cats naturally do not have a diet high in carbohydrates, and therefore, their saliva does not contain the enzyme amylase. [ 31 ]

Establishment of the forelimb field (but not hindlimb field) requires retinoic acid signaling in the developing trunk of the embryo from which the limb buds emerge. [ 2 ] [ 3 ] Also, although excess retinoic acid can alter limb patterning by ectopically activating Shh or Meis1/Meis2 expression, genetic studies in mouse that eliminate retinoic ...
They may or may not perform the same function. An example is the forelimb structure shared by cats and whales. Analogous structures - structures similar in different organisms because, in convergent evolution, they evolved in a similar environment, rather than were inherited from a recent common ancestor. They usually serve the same or similar ...
