2. it is a tool to emphasizes the functional and evolutionary.
3. closest to the body.
5. is restricted to mean the action or property of a part as it works in an organism.
7. applies to two or more features that share a common ancestry.
9. refers to the tail.
12. a tree diagram, especially one showing taxonomic relationships.
13. Anatomy deals with anatomy and its significance
17. derived from more than one common evolutionary ancestor or ancestral group and therefore not suitable for placing in the same taxon.
20. also called as segmentation
21. refers to the sides.
23. Symmetry refers to a body that is laid out equally from central axis.
24. the mid-line of the body.
26. descended from a common evolutionary ancestor or ancestral group, but not including all the descendant groups.
27. to features with a similar function.
29. the branch of science concerned with fossil animals and plants.
30. to features that simply look alike.
32. is the study of relationships among different groups of organisms and their evolutionary development.
33. is simply a named group of organisms.
35. Symmetry it devides the body into two mirrored images.
36. also called phylogenetic systematics.
37. a body or structure built of repeating or duplicated sections.

1. is the term that has been coined to recognize the importance of ecological analysis in the examination of a morphological system.
2. is a lineage—all organisms in a lineage plus the ancestor they have in common.
4. refers to the head.
6. the study of the forms of things.
7. swimming strokes.
8. is the process of an animal or plant becoming preserved in a hard, petrified form.
10. is the study of how decay and tissue disintegration affect fossilization.
11. refers to the belly or front.
13. used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
14. refers to the back.
15. sweeping side to side movements of tail.
16. Selection the mechanism of evolution.
18. a method of placing fossils in a relative sequence to each other
19. describes the way in which an animal's body meets the surrounding environment.
22. an attached appendage has a region farthest.
25. Darwin he proposed the conditions for and mechanism of this evolutionary change.
28. or monophylogeny, is a term used to describe a group of organisms that are classified in the same taxon and share a most common recent ancestor.
31. the scientist who felt that species were fixed and unchangeable.
34. electric record of the muscle.
