Final answer:

Descent with modification is a key concept in evolutionary biology explaining how organisms evolve from common ancestors with slight changes in traits and genetic codes.


Explanation:

Descent with modification is a fundamental concept in evolutionary biology that explains how organisms evolve from common ancestors and diversify over time by acquiring slight changes in their traits and genetic codes. This process leads to the formation of new species while maintaining some shared characteristics with their ancestors. Phylogenetic trees help scientists track these evolutionary relationships and understand the concept of descent with modification.
