Flashcards in 2/2/17 lecture: evolution IV: ways of studying evolution contineud Deck (14):
1

gorilla

herom polygynay, one male, many females, does not need as long of penis or large testes bc he can get all he wants

2

chimp

sperm competition, bigger testes means more chances of impregnating femal

3

human

monogamy - separate fertilization, long penis size mm competition

4

orangatan

seasonal monogamy

5

other ways of studying evolution

biogeography, developmental ibology, artificial selection, phylogenetics

6

biogepgraphy

pattern - look at species biodiversity - not spread perfectly throughout planet - similarities

7

endemic specieis

no speicies found anywehre else bc of isolation

8

ocntinental drift

some speicies on same plate

9

wallace's line

speiceis on one side similar but v different from other side

10

artifical selection

pigeons, corn, organisms have heritable variation can act on

11

developmental biology

developmental sequence reflected in organisms - ie. squirrel, fish, frog - ciruclatory system - aortic arches; ernst hakel's "biogenic law" - we are fish et before humans - ontogeney recapitualtes phylogeny

12

phylogenetics

reconstruction of evolutionary relationhsipps, find where common ancestor is, how recent / distant ancestor is

13

character states examples

long/short, yellow/brown - physical characteristics

14

characters

body length, attanae
