A person walking through airborne dust in, say, a cosmetic plant can possibly become dangerously charged by contact with the floor and various objects that are touched. The first, well-documented man-made hybrid was a Dianthus, produced in 1716, when Thomas Fair-child crossed Dianthus caryophyllus (Carnation) with D. barbatus (Sweet William). A population of mountain lions may vary in several characteristics. In the monophyletic genus Geospiza, the most basal species, the sharp-billed ground finch Geospiza difficilis has a small symmetrical bill, whereas the more derived ground finches have deep and broad bills to crack hard seeds, and cactus finches have elongated and narrow bills for penetrating cactus flowers (Grant & Grant 2008). Other examples include human birth weight, the number of eggs a bird lays, and the density of cactus spines. group selection The controversial idea that natural selection can sometimes act collectively via benefits realized by entire groups of organisms, as opposed to the narrower fitness benefits realized by selection acting only on individuals.

The stabilizing process is one that results statistically in an over-represented norm. Homozygous recessive nn cacti have no spines at all. Convergent evolution is the process in which organisms that are not closely related independently evolve similar features. Stabilizing selection works mostly on traits that are polygenic. Selection is perhaps the best known of the processes affecting genetic diversity and is the only process that directly results in populations becoming better adapted to their environment. The female calves resulted from the . When I pick up the urchin, I easily return to the sharp black lava rock that borders the path to the sea.
