Question

-

Biochemical analysis uses similarities in
as evidence for evolutionary relationships.
A)
DNA sequences
bone structure
cellular architecture
D)
homologous structures
For finches on the Galapagos, a significant change in beak size can be observed across years with plentiful rainfall
or intense drought. How can the changes in finch beak size be attributed to evolution?
Finches on the island with better adapted beak sizes have increased
survival
Finches on the island are domesticated and are artificially selected for
beak size.
Finches on the island without well suited beak sizes change their diet to
induce and enhance growth of their beaks.

Answer 1

A-DNA sequences

Step-by-step explanation:

The biochemical analysis use similarities in DNA sequences as evidence of evolutionary relationships. Scientists ascertain that the two species with almost the same protein structure are more relates with one another i.e., they might have evolved from a common ancestor. Evolutionary relationship show common ancestor for population and species using molecular evidences.
