Question

Explain with suitable examples importance of anatomical and evidences in evolution

Answer 1

Anatomical evidence is important as a physical proof for evolution. The anatomical evidence are majorly of two kinds:

Analogous structures: These are structures that have similar functions and appearance but have different biological make-up. This is a proof for evolution that unrelated species, when forced to live in similar conditions, adapted to this- but differently. examples- Body shape, size and colour in sharks and dolphins

Homologous structures: these are structures with similar biological make-up but different functions. This supports evolution that related species when exposed to different environments, adapted accordingly. examples: Wings of birds and bats

Answer 2

Answer:

There doesn't seem any superficial similarity between a human, a cat's foreleg, flipper of whale and patagium of bat. use of each of these structure is different in respective animals. however there is similarity in structure of bones joints in organs of each of these animals. the similarity indicates that these animals show anatomical evolution.

hope it help.
