According to comparative morphology,

all organisms have similar development
the more closely related two species, the more analogous structures they will share
homologous structures are inherited from a common ancestor
organisms which have vestigial features are related to one another

homologous structures are inherited from a common ancestor.

Explanation:

According to comparative morphology, homologous structures are inherited from a common ancestor. They also show similar pattern in in their embryological development.

Homologous structures are the similar structures due to shared ancestry. The organism with homologous structures are all the descendants of a common ancestor.

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)
