In any population variation exists and much of this variation is heritable. Individuals with more favorable traits are more likely to reproduce and these inherited favorable traits become more common in succeeding generations. Individuals of a species naturally select the habitat and niche to which they are best suited. There is random mating in a population and no selection for or against either member of an allelic pair. The co-developer of the theory of natural selection was a. Lamark.
Cladistics is a. a method for developing phylogenetic trees.
Male fireflies attract mates by flashing a signal with their luminescent abdomen as they fly through the air. Each species has its own pattern of flashes which can be easily distinguished from that of other species. You can often observe males of several different species trying to attract females at the same time and in the same area. The different species do not hybridize, however, because females respond only to males of their own species. This is an example of a. habitat isolation.
