Answer:
D- Indicates common ancestors
Explanation:
A phylogenetic tree shows evolutionary relationships among organisms. This tree establishes the common ancestry and divergence points of each species from the common ancestor. These relationships are not definite facts and do not show the exact time of divergence among species of common ancestry.
The pattern of branching in a phylogenetic tree shows how species or other groups evolved from a series of common ancestors. Two species are more closely related, if their ancestral link is more recent and less closely related if their ancestral link is less recent.
A phylogenic tree, uses branches to establish the relationships between common ancestors and species, each branch point, indicating common ancestry among offspring. The farther the branch points from the common ancestor and other members of the species, the farther the relationship among them.
Answer: Option D.
Explanation:
A phylogenetic tree is a brach diagram that shows the relationship among species of organisms in a taxa base on their differences and similarities of physical characteristics and genetic characters indicating common ancestors.
The tips of the tree represent descendents of the taxa and the node represent the common ancestors of the descendants. It uses branches to represent relationships among species, common ancestors and also descendants of the ancestors.
