ANTB14H3 Lecture Notes - Lecture 3: Reproductive Isolation, Macroevolution, Fetus
Document Summary
Associated with research on the formation of new taxonomic groups. Large-scale changes at or above the special level. Similar-looking individuals that can successfully produce fertile offspring lumped into discrete species categories. Actually or potentially interbreeding populations (mayr, 1942) Must apply all known morphological, behavioural, and ecological data to use as deductive proof of reproductive isolation between species. Definition = actually or potentially interbreeding populations which are reproductively isolated from. E. g. , a rat mating with an elephant - wont happen = reproductive isolation other such populations. First starts with mate selection - rate does not see elephant as a possible mate. Scenario with monkey - when one species of moneky see another species of monkey, they do not see them as a potential mate. Different cues to provent mate recognition across other species (size, height, colour, tail) Monkeys have sexual behaviour too that have preferences. Have sex with other species and no zygote is formed.
