4. body cavities in animals, formed early in embryogeneis
5. towards head
8. The history of organisms across time
9. side to side
10. Determining similarities and differences between organisms
13. similarity due to common function
14. certain adaptive features or attributes are inherited from ancestors and passed on as modifications to descendants
16. Common ancestor not included in grouping
19. Arthropods that are part of a well-supported group of three phyla
23. history of organisms across space
27. median line
28. growth towards the tail end
29. nested part of phylogenetic tree

1. hypotheses; can be constructed to visualize the predicted relationships between species, genes in a gene family, populations, cell lines, or any other number of levels of biological organization.
2. similarity due to common ancestry
3. top of body
6. Ancestor + some, but not all descendants
7. one common ancestor + all its descendants
11. The history of organisms across development
12. A cross-lineage approach to understanding the phylogenetic history of organisms based on patterns and mechanisms, and what drives the evolution of those
15. underside of body
17. close to body, where leg attaches to body
18. invertebrate organ for removing metabolic waste; kidney
20. away from body like tarsi
21. molting animals
22. defined segment of the nervous system
24. towards tail
25. a shared derived character; a homolog applied at a particular level of universality
26. segmented animals
