Asked by Blake E Palmer Student at University of Tennessee How are biodiversity patterns related to speciation processes? As of now scientists have named about 1.5 million species on Earth but estimate that 5 to 100 million species exist. Speciation plays a huge and urgent role in research now due to the high amount of animals going extinct or becoming endangered. According to the textbook speciation is defined as the evolution of two or more distinct species from a single ancestral species. As species become known and more species are found our biodiversity continues to grow, and it will continue to grow since there are so many species that have not been named. Even though we have many unknown species were are running into huge problems regarding the species we do have named. Due to human made threats, many animals face extinction so we will have less species. According to Roger K. Butlin, Jon R. Bridleand Dolph Schluter "It [speciation] can occur in a single step, such as bypolyploidy, or it may occur by a gradual series of allelic substitutions at multipleloci. It can happen as a by-product of adaptation to contrasting niches orenvironments, or it can happen without any adaptation at all." These forms of speciation are impacting our biodiversity but in what ways?
