Document Summary
Ecology: evolution in the present moment: what is ecology, why talk about ecology in an evolution course, adaptations are affected by the biotic and abiotic environment. Large scale climate patterns: global patterns in temperature and precipitation, seasons. Variation in climate patterns: local variation in climate, global variation in climate, stochasticity. Many generations later, after mutations, recombinations, drift, gene flow, selection, etc. there"s 14 species. Subtle changes to male songs: abiotic. Variation in local conditions: intensity of sunlight on earth varies. Equator is the warmest part because of angle of sun"s rays. Area of sunlight hitting equator is smaller and more concentrated than at the poles. Less atmosphere to travel through at the equator: effect of light intensity on temperature. The more intense and concentrated the sunlight is on an area, the warmer it"ll be: effect of light intensity on rain.
