Phylogeny and Systematics

Name the term: evolutionary history of a species or group of related species

Name the term: analytical approach to understanding the diversity and relationships of organisms, both present day and extinct

What do systematists use to infer evolutionary relationships? (Hint: there are multiple correct answers)

• fossils

• behavioral, mating, and genetic comparisons

• morphological, biochemical and molecular comparisons

• previous evolutionary books/papers and experiments

Name the term: similarity due to shared ancestry

Name the term: similarity due to convergent evolution

Name the term: occurs when similar environmental pressures and natural selection produce similar (analogous) adaptations in organisms from evolutionary lineages

Name the term: ordered division of organisms into categories based on characteristics used to assess similarities and differences

Name the term: the two-part scientific name of a species

Name the term: first part of the binomial nomenclature

Name the term: the second part of the binomial nomenclature; unique for each species within the genus
