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.
This could produce a number of individuals that have a mutation that would make them unable to deal with life in that environment. Or the same change would allow them to do exceedingly well. This mutation would, over a very long time, produce a different species. Speciation that results when a population is separated by a physical barrier is allopatric speciation. Sympatric speciation is speciation that occurs without physical separation of members of the population. Some examples of sympatric changes occurred long ago when people live in small villages.
