Darwin's finches are an ancestral mainland finch species that arrived on the galápagos islands and evolved into about 15 new species through adaptive radiation, while the finches on the mainland did not. what is the most plausible biological explanation for this?
options:
a- adaptive radiation happened because of the isolation of the islands.
b- lack of competition on the island allowed for greater utilization of resources by the finches.
c- the environment on the mainland was completely uniform, unlike the galápagos.
d- the founder effect greatly expanded the variation in alleles in the galápagos finch gene pool.

According to the big bang theory, after the "bang," the universe remained dark until about  300,000 yearsone billion yearsthree minutesthree billion years  later, when neutral atoms began to form.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
