Question

meredith e. protas and colleagues have explored how convergent evolution - a phenomenon that occurs when the same trait evolves independently in two reproductively separate lineages - can result from a genetic mechanism shared by both lineages. meanwhile, cynthia c. steiner and colleagues have investigated how convergence occurs through different genetic mechanisms, but the relative prevalence of convergence through shared and different genetic processes is still poorly understood. this motivated biologists delbert a. green ii and cassandra g. extavour to evaluate both types of convergence in a single study for their 2012 paper. according to the text, what did protas and colleagues focus on in their study? a) convergent traits arising from different genetic mechanisms b) convergent traits arising from a shared genetic mechanism c) the convergence of traits in lineages that are not reproductively separate d) the relative prevalence of convergent traits emerging through shared and different genetic mechanisms

Explanation:

The text describes a study on convergent evolution, focusing on how the same trait evolves independently in different lineages. It mentions that Protas and colleagues investigated the relative prevalence of convergence through different genetic mechanisms. They aimed to evaluate both types of convergence in a single study as genetic processes of convergence are still poorly understood. The study focused on convergent traits arising from different genetic mechanisms.

Answer:

A. Convergent traits arising from different genetic mechanisms
