Document Summary
Crickets chirping: chirps + 40 = temperature. Why study animal behaviour: review of last class, understanding adaptiveness and diversity of animals, behavioural changes, applied behaviour and also to understand human behaviour, critical knowing. An evolutionary approach: adaptation and fitness, successful ancestors all the way down the line, singing in unison will monitor the animal population, phenomenon in europe. Increase of population and then it outbreed the food supply and then the lemmons will migrate. Jumping down into the ocean and then they died. Yet: suicide occurs in nature: suicide does evolve in nature in certain circumstances, hornets, wasps, bees are stingers, bees stinger are attached to their guts and they will die after stinging you. Worker bee always eviscerated when using sting to defend hive: wood cricket example. Worm infested crickets dive into a pool and drown: red back spider example. The tiny red back spider male somersaults into his mate"s jaws after mating.
