Question

Which of the following are true about phylogenetic trees?

1. They're a way of visualizing how different populations are related.
2. The species to the right are more evolved than the species to the left.
3. All of the above.
4. None of the above

Answer 1

Answer:

answer is the 2nd option

diagram or "tree" showing the evolutionary relationships among various biological species or other entities—their phylogeny —based upon similarities and differences in their physical or genetic characteristics.

Answer 2

The species to the right are more evolved than the species to the left. (Option 2)

• The most ancestral branch in the tree has no endpoint of a branch that represents a living or extinct group of genes.
• A taxon that diverged before the taxa that are the focus of the study helps to root the tree.
• All the nodes that depict an ancestral branch dividing into three or more descendant branches usually indicate that insufficient data were available.
• A point within the tree where a branch splits into two or more branches that represents the most common ancestor of the descendant groups.
