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.
Grant (1986) proposed a three-step process to speciation to explain the adaptive radiation of the group: (i) The ancestral species arrives in the archipelago; (ii) the species spreads to other islands and as a result of this, there will probably be some selection and hence differentiation in size because the islands are different; and (iii) members of the original and derived populations encounter each other, and as a result of competition for food and selection against intermediates ...
