which are similar structures shared by different
evidence for evolution includes the presence of
species
gradual structures
vestigial structures
integrated structures
homologous structures

The correct option is D) homologous structures

Explanation:

In evolutionary studies, a homologous structure can be described s a similar structure which is present in different species. This is because these spices might have a common ancestor in the past. For example, the forelimbs of humans and bat. They perform different functions but their structure is similar. They are also derived from the same embryonic origin. These similarities show that the bats and humans might have shared a common ancestor in the past.
