Question

what principle does the grants investigation of finch adaptation in the galapagos islands best support?
madeleine
m
evolutionary
evolutionary
uniformitarianism
natural selection
biogeography

Explanation:

The Grants' study on finch adaptation in the Galapagos focused on how different beak shapes (and other traits) evolved due to environmental pressures (like food availability), which is the core of natural selection. Evolutionary embryology is about embryo development in evolution, uniformitarianism is about geological processes, and biogeography is about species distribution. So natural selection is the principle supported here.

Answer:

natural selection
