Question

Some molecular data place the giant panda in the bear 2points family (Ursidae) but place the lesser panda in the raccoon family (Procyonidae). If the molecular data best reflect the evolutionary history of these two groups, then the morphological similarities of these two species is most likely due to what? Your answer

Answer 1

The options

(a) inheritance of acquired characteristics

(b) sexual selection

(c) inheritance of shared derived characters

(d) possession of analogous structures

(e) possession of shared primitive characters

The CORRECT ANSWER IS (d)

(d) possession of analogous structures

Step-by-step explanation:

In evolutionary biology, analogous structures are referred to as biological structures with similar or equivalent function but of different evolutionary origin. That is to say, these species employs these biological structures for the same reasons even though they are from independent evolutionary lines.

Convergent evolution results in analogous structures with similar form or function that is absent in the last common ancestor of those groups. Take for example, Bird, bat, and pterosaur wings are analogous structures, and have forelimbs to be homologous, possessing an ancestral state not regarding it's differing functions.

The giant panda and lesser panda do reflect convergent evolution in areas of which they possess morphological structures of similar functionality. Thus, they have been categorized into two unique families, which is a factor of their DNA sequencing

So, the correct answer is 'possession of analogous structures.'
