In this locale, two types of cichlids live in the same geographic location; however, they have come to have different morphologies that allow them to eat various food sources. Explain your choice. This shows grade level based on the word's complexity. Change in the genetic variation for beaks in response to natural selection based on specific food sources in each new habitat led to evolution of a different beak suited to the specific food source.

What species concept, can the graduate student use to make the case that the two similar-looking hominin samples, ? From one point of origin, many adaptations evolve causing the species to radiate into several new ones. Sympatric speciation, meaning speciation in the same homeland, involves speciation occurring within a parent species while remaining in one location. Under pressure to find food, suppose that a group of these fish had the genetic flexibility to discover and feed off another resource that was unused by the other fish. Source: martindxmguide.blogspot.com. For example, if a plant species with 2n = 6 produces autopolyploid gametes that are also diploid (2n = 6, when they should be n = 3), the gametes now have twice as many chromosomes as they should have.
