Document Summary
Need to look at perception to see what animals are doing at higher level of cognition. Animals need to be able to perceive what is around them, discriminate between relevant stimuli, and pay attention. In order to survive, animals need to avoid getting eaten. Buster needs to eat to survive and pass on its gene, while bubbles needs to run away to survive and pass on its gene. Sexual selection: peacocks have evolved to look the way they do because female"s prefer colorful looks. Senses animals have that human"s don"t have: electric sense platapus, echolocation bats, magnetoception bees. Use sound waves above human audible hearing range. Send out high frequency waves to spot prey. A bat directs its sonar beam at a target. It perceives the returning waves (echoes) to detect the location of the prey (moth: it determines the location of a prey by comparing the returning waves that echo back to the waves that it initially sent off.
