In addition, any one behavior could be identified differently by different observers. A sign stimulus and a releaser are very similar in that they are both types of stimuli which elicit a fixed action pattern. Describe three ways in which the barn owl is specialized to localize sounds.
Some moths produce high frequency sounds in the range of bat sonar pulses.
Explain this in terms of natural selection of the moth. The bats have learned, or maybe have an innate knowledge, that some moths aren't suitable meals through the moth's high frequency sounds. This has the effect of allowing the moths capable of this form of communication to avoid predation and to survive in order to reproduce. Subsequently, more alleles for the moth sonar behavior are represented in the gamete pool, which increases the frequency of this behavior or maintains the behavior in a natural population. Since we only have 1 allele per gene and there are 6,000 genes then we have only 6,000 alleles on the chromosome 7.
