Relier Pairs Systematics MatchingVersion en ligne Exam 1 definitions systematics par Emma Fuller 1 classification 2 evolutionary 3 biodiversity 4 phylogeny 5 competing philosophies 6 taxonomy 7 cladistics 8 systematics different schools of thought that promote different theories, principles, or methods Taxa should share recent common ancestry AND morphological similarity, may generate some paraphyletic taxa evolutionary history Study of diversification and relationships Assigning organisms to hierarchical groups number of species, genre, etc All taxa should be clades, monophyletic AND holophyletic the naming of groups of organisms 1 autapomorphic 2 monophyletic 3 synapomorphic 4 grade 5 analogous 6 paraphyletic 7 clade 8 plesiomorphic 9 polyphyletic 10 homoplasy 11 holophyletic 12 symplesiomorphic 13 apomorphic 14 homologous A group of organisms that shares similarity but not by shared common ancestry or excluding some descendants Similar based on shared common ancestry A lineage or trait found in independent lineages A lineage including some but not all descendants of a single common ancestor shared, derived characteristic Similar due to common function, not based on shared common ancestry An analogous trait or character, such as skin flaps for gliding A lineage of organisms that is derived from a single common ancestor and contains ALL descendants An unshared, derived characteristic A lineage including all descendants of a single common ancestor A lineage with a single common ancestor An ancestral characteristic A shared, ancestral characteristic A derived characteristic 1 bradytely 2 phylogram 3 convergent evolution 4 tachytely 5 dendrogram 6 DKPCOFGS 7 cladogram 8 horotely 9 parallel evolution a diagram that shows the evolutionary relationships between species, and is also known as a phylogenetic tree. Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species a biological term that describes a normal or average rate of evolution for a group of plants or animals a branching diagram showing the cladistic relationship between a number of species a branching diagram that shows how similar a group of things are to each other The evolution of analogous characteristics in distantly related clades The evolution of homologous characteristics into new forms/phenotypes in the same clade. “Descent with modification” evolution that is very slow or has stopped evolution at a relatively rapid rate tending to result in speedy differentiation and fixation of new types
