Gellan Gum is a water-soluble polysaccharide produced by fermentation. This multifunctional gelling agent can be used alone or in combination with other products to produce a wide variety of interesting textures.
Evolution is a process that explains how organisms have diversified and descended from earlier forms of organisms over time. Essentially that means all species living on earth have derived from a common ancestor. Speciation is an evolutionary process that leads to the formation of a new species. Natural Selection and Speciation For a new species to form, individuals of a population need to be reproductively isolated from one another.
Lesson Summary. Though not common, sympatric speciation is an important evolutionary process that can separate a species into two new ones. This is a relatively uncommon form of speciation, though it has been observed in hawthorn flies and orcas.ympatric speciation occurs if interactions are so limited between these groups that mating no longer occurs between them. Each new population of flies will have genetic variation in its gene pool, which is the collective genetic information for the group.
