Descent with Modification Video Lessons

Concept

# Problem: Members of two different species possess a similar-looking structure that they use in a similar fashion to perform the same function. Which information would shed the most light on whether these structures are homologous or whether they are, instead, the result of convergent evolution?a. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identical.b. Both species are well adapted to their particular environments.c. The sizes of the structures in adult members of both species are similar in size.d. Both species reproduce sexually.e. The two species live at great distance from each other.

b. Both species are well adapted to their particular environments.

c. The sizes of the structures in adult members of both species are similar in size.

d. Both species reproduce sexually.

e. The two species live at great distance from each other.
