The brown beetles had developed more advantageous traits that allowed them to have more offspring and less vulnerable to predators. Therefore, living organisms continue to become new species through natural selection working on mutation.
Genetic drift is among the main mechanisms force that drives evolution thus resulting in the appearance of new species. Genetic drift operates on a random chance where a certain population of an organism may be affected by ecological disasters. Imagine there is a breeding population of 100 in a given area and the volcanic eruption occurs it will possibly kill every organism that is close as there is no organism in the population that has adaptation toward this kind of calamity (Goodall 159). Therefore, half of the population might die, and the remaining population will result in the appearance of new species as individuals who have remain will possibly lack the exact alleles as the whole population had before the occurrence of the calamity.
Evolution comprises two processes which are cladogenesis and anagenesis, and these two process are essential at describing how new species came to appear either as from a single lineage or from the branching lineage. Anagenesis is a process that describes how species can evolve from a single lineage, as the population continues to develop new traits. Cladogenesis, on the other hand, describes the budding of new species from parent species that continue to exist.
i. Solitary or noyau is one of the natures in which primates have tried to use thus adapting the environment conditions fundamental for survival. Orangutans are an example of the primate that lives a more solitary lifestyle, and most social-link take place between an adult female and they're dependent who lives in the home range (Goodall 247). It is fascinating to recognize Orangutan society protects itself as everyone resident home range of female it covered with another home range.
