Document Summary
Classification: kingdom- animalia, phylum- chordate, class- mammalian, order- primates, family- hominidae, genus- homo, species- h. sapiens. Concept 26. 2: phylogenies are inferred from morphological (based on the physical shape, anatomical/developmental structure) and molecular data (how similar our. Dna is; only big for the past 40 years) how did we decide to group these organisms: we use to look at physical structures of organisms, but now we use dna. Concept 26. 3: shared characters are used to construct phylogenetic trees. Cladistics-about putting together a cladogram: cladogram: a diagram depicting/illustrating patterns of shared characteristics among species, clade within a cladogram: a group that includes an ancestral species and all of its descendents, a valid clade is monophyletic. Monophyletic grouping: made up of an ancestral species and all of its descendents, node= ancestral species, a,b, and c are all the species that came from that species, clades have to be monophyletic.
