Natural & Sexual Selection: An Illustrated Introduction, Email us to have your account info removed from Labs. The topics covered include adaptation, natural selection by predation, speciation, and reproductive barriers. Many species are similar enough that hybrid offspring are possible and may often occur in nature, but for the majority of species this rule generally holds. In fact, the presence of hybrids between similar species suggests that they may have descended from a single interbreeding species and that the speciation process may not yet be completed. In some cases, a population of one species disperses throughout an area, and each finds a distinct niche or isolated habitat. Admin March 19, 2021. NOTE: The Deep Tree is an open-ended activity with no time commitment.

Sympatric speciation, meaning speciation in the same homeland, involves speciation occurring within a parent species while remaining in one location. See page 493 of your text for the labeled figure and examples. Finally, a well-documented example of ongoing sympatric speciation occurred in the apple maggot fly, Rhagoletis pomonella, which arose as an isolated population sometime after the introduction of the apple into North America. In some cases a polyploid individual will have two or more complete sets of chromosomes from its own species in a condition called autopolyploidy (Figure 11.17).

NOTE: The interactive lessons are online versions of the worksheets and contain the same questions. There is no reason why there might not be more than two species formed at one time except that it is less likely and such multiple events can also be conceptualized as single splits occurring close in time.

In NOVAs Evolution Lab, students will explore the evidence of evolution through the lens of phylogeny. Island archipelagos like the Hawaiian Islands provide an ideal context for adaptive radiation events because water surrounds each island, which leads to geographical isolation for many organisms (Figure 11.16). Two matings are necessary to produce viable offspring. Natural selection plus geographical and ecological isolation has undoubtedly been operative in speciation and in subspeciation.
