ResetHelp convergent evolution molecular systematics shared derived characters monophyletic group phylogeny shared ancestral characters analogy 1. is the evolutionary history of a species or group of species. 2. can produce similarities in body form when similar environments and natural selection have favored similar adaptations. 3. Distinguishing between homology, which reflects common ancestry, and , which does not, is critical in determining evolutionary relationships. 4. A(n) is a group of species that includes an ancestral species and all of its descendants. 5. distinguish clades and thus branch points in the tree of life. 6. The use of DNA and other molecules to determine evolutionary relationships is called .

Answers:

1. phylogeny

2. Convergent evolution

3. Analogy

4. monophyletic group

5. Shared derived characters

6. Molecular systematics

Explanation:

1. phylogeny

In biology, phylogeny has to do with the evolutionary history and relationships within individuals or groups of organisms

2. Convergent evolution

It is the independent evolution of likely features in species of seperates periods or epochs in time. It develops an analogous structures thatshow a look alike form or function but were absent in the previous common ancestor of those groups

3. Analogy

It deals with similarity of function and superficial appearance of body form that have possess distinct origins. E.g. the wings of a fly, a moth, and a bird are analogous since they are formed independently as adaptations to a perform an activity—flying

4. monophyletic group

It is made up of all the descendants of a common ancestor. It distinctly has shared derived characteristics, which groups species in the clade from other species

5. Shared derived characters

A shared character is the similarities between two lineages , and a derived character is the evolved in the lineage that forms and distinguishes a clade. Shared derived characters is employed to classify organisms into clades

6. Molecular systematics

This employs molecular genetics to obsereve the evolution of relationships between organisms. It gives knowledge into the organisms history and how its evolution could have formed diversity among organisms.
