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.
Punctuated equilibrium can be accommodated within the classical neo-Darwinian synthesis as an end-member of the spectrum of possible evolutionary events that lead to the appearance of new species. But it's not the only possible mode of speciation: it is one possible mode. There's no intrinsic reason that evolutionary change should occur only in small populations, and there's no evidence that populations that have undergone marked evolutionary change are any smaller than those that are stable.
