Quizzes with auto-grading, and real-time student data. Diversifying (or disruptive) selection: Diversifying selection occurs when extreme values for a trait are favored over the intermediate values.This type of selection often drives speciation. There are multiple ways to define the concept of "species." The choice of definition is dependent on the particularities of the species concerned. 1. Terms: distribution, speciation, phylogenetic tree, evolution 1) Identify patterns in biological data, such as morphological characters (physical features), habitat, and geographical distribution. HS-LS4-4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.HS-LS4-5 Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species. Theres some debate about how important or common a mechanism it is, but the answer appears to be yes, at least in some cases. However, one mechanism that's quite commonin plants, that is!involves chromosome separation errors during cell division.

These mechanisms can lead to each subpopulation becoming so different, that they can no longer interbreed and are considered separate species.

Boggs, in International Encyclopedia of the Social & Behavioral Sciences, 2001 3.2 Parapatric Speciation 'Parapatric' derives from 'para' meaning 'near' and 'patria' meaning 'country.' Parapatric speciation thus occurs when a smaller population is isolated, usually at the periphery of a larger group, and becomes differentiated to the point of becoming a new species. We have documented many examples of this type of, geographic barriers would have led to the finch, Different species of these birds live on different islands in the, Galpagos archipelago, located in the Pacific Ocean off South. That is, organisms are usually considered to be members of the same species if they can successfully reproduce with one another. It is the process by which an ancestral species splits into two or more new species. This most often occurs due to geographic isolation or reproductive isolation of individuals within the population. For example, one scenario reads Squirrels on the Kaibab plateau cannot easily reach the valley where gray squirrels live. Speciation occurs across the range of spatial contexts summarized by the allopatric to sympatric continuum, but most speciation is associated with geographic separation. Some of its most exciting insights have come from the crossover of disciplines as Two species might prefer different habitats and thus be unlikely to encounter one another. In other cases, a hybrid can survive to adulthood in good health but is infertile because it can't split its mismatched chromosomes evenly into eggs and sperm.
