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