Question

which of these is the best description of \descent with modification\?

the way organisms descend from a common ancestor just with slight modifications
a structure that is the same in all organisms just with small differences in its purpose
a type of process that causes organisms to get larger and larger over time

Explanation:

"Descent with modification" is a key concept in evolutionary biology. It refers to the idea that organisms share a common ancestor and have evolved over time with slight changes. The first option correctly captures this essence as it emphasizes the descent from a common ancestor with modifications. The second option describes homologous structures rather than the overall concept of descent with modification. The third option is incorrect as "descent with modification" is not about organisms simply getting larger over time.

Answer:

the way organisms descend from a common ancestor just with slight modifications
