Question

Describe the two fields of study. Compares the genomes of different organisms compares the limbs of different organisms compares fossilized structures to living organisms compares cells of organisms.

Answer 1

It is assumed that organisms with similar anatomical characteristics have evolved relatively recently and have a common ancestor.

How does comparing the physical characteristics of different creatures help us understand evolution?

To comprehend how living things originated, scientists study the anatomy, embryos, and DNA of various species. Homological structures provide proof of evolution. These are features that were passed down from a common ancestor and are shared by related creatures. An further piece of evidence for evolution is offered by similar structures.

What role does anatomy play in the study of relationships between various types of organisms?

Comparative anatomy, which compares structural similarities, is one of the strongest types of evidence of creatures to ascertain the links between them throughout evolution. It is assumed that organisms with similar anatomical traits have evolved from ancestors who were reasonably closely connected to one another.
