Similar (analogous) structure or molecular sequence that has evolved independently in two species. - 3SystematicsThe analytical study of the diversity and relationships of organisms, both present-day and extinct.
- 4Taxonthe named taxonomic unit at any level of the hierarchy
- 5CladogramA diagram depicting patterns of shared characteristics among species.
- 6CladeA group of species that includes an ancestral species and all its descendants.
- 7(Maximum?) ParsimonyA principle that states that when considering multiple explanations for an observation, one should first investigate the simplest explanation that is consistent with the facts.
- 8rRNA vs. mt DNARNA component of the ribosome, and is essential for protein synthesis in all living organisms.
the DNA located in mitochondria; cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, ATP. - 9MonophyleticPertaining to a grouping of species consisting of an ancestral species and all its descendants; a clade.
