Introduction to Diversity
Transcript of Introduction to Diversity
Haeckel, 1866 Monophyletic group: ancestral species and ALL descendants (ex: all reptiles, including birds)
Paraphyletic group: ancestral species and SOME descendants (ex: non-avian reptiles)
Polyphyletic group: lacks a common ancestor (ex: warm-blooded animals [birds and mammals]) Cladogram Maximum Parsimony The most correct tree has the fewest independent evolutionary events
Also called Occam's Razor Not always true... Clade: Group of related species Species begin divergence from common ancestor Mutations! DNA sequences don't look very similar anymore.... but computers are really smart. (actually its the programmers)
