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