Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What type of evidence did was most likely use to reach his conclusion of species with similar DNA are closely related?

A	fossil evidence
B	structural evidence
C	genetic evidence
D	evidence from developmental patterns

Explanation:

Detailed explanation-1: -DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Detailed explanation-2: -Darwin used multiple lines of evidence to support his theory of evolution by natural selection–fossil evidence, biogeographical evidence, and anatomical evidence.

Detailed explanation-3: -Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor. More similarities in the DNA sequence is evidence for a closer evolutionary relationship.

Detailed explanation-4: -Evidence from Fossils The fossil record reveals how horses evolved. The lineage that led to modern horses (Equus) grew taller over time (from the 0.4 m Hyracotherium in early Eocene to the 1.6 m Equus). This lineage also developed longer molar teeth and the degeneration of the outer phalanges on the feet.
