Question

the illustrations are of four different galápagos islands finch species that charles darwin claimed originated from a single ancestral species. he collected and documented much data from his observations while exploring the islands. he also included research species from these islands that displayed the same type of divergent evolution.which of the following statements best explains the claim that different finch species originated from a single ancestral species?○ recessive traits in the finch populations were eliminated over time due to the presence of dominant traits.○ offspring numbers declined, which resulted in the presence of new genotypes○ unique characteristics were acquired by individual birds during their lifetimes.○ a variety of desirable traits were exhibited because of adapting to different environmental pressures.

Explanation:

Divergent evolution of Galápagos finches is driven by natural selection: as ancestral finches spread to islands with distinct environmental pressures (like different food sources), traits suited to each environment became more common. Over time, this led to the formation of different species with unique traits. The other options are incorrect: recessive traits are not eliminated by dominant ones in this context, acquired characteristics during a lifetime are not passed on (Lamarckian, not Darwinian), and declining offspring numbers from new genotypes does not explain speciation.

Answer:

A variety of desirable traits were exhibited because of adapting to different environmental pressures.
