Question

Related species have similar body structures because they inherited the same genes from a common ancestor. True False

Answer 1

Answer: True

Explanation:

The related species have the similar body structure because the species inherit same gene from the common ancestor.

The species carry the same gene responsible for the characters which is carried generation after generation.

Example: The genes responsible for the limbs is carried from one generation to another in different-different organisms.

Answer 2

Answer: True

Explanation:

According to the theory of evolution the traits are passed from one generation to the other during the course of evolution. The related species are expected to have a common ancestor due to presence of homologous structures. The homologous structures are those structures which have the same structure but different function. The homologous structures help in supporting the evidence that modern day organisms have evolved from primitive organisms.
