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 is why speciation is considered to be a macroevolutionary process, as it involves the divergence of a new phylogenetic line (i.e. a new species) from an existing one. This is also why the post on macroevolution on my blog includes examples of speciation as macroevolution.
