Chapter 2 Variation Under Nature In the book‚ The Origin of Species‚ by Charles Darwin‚ he explains variation under nature‚ examining if the variety in species in nature can be possibly similar to the variety in domesticated species. Charles Darwin said‚ “The term “variety” is almost difficult to define; but here community of descent is almost universally implied‚ though it can rarely be proved.” He explains how people use the word monstrosities which he presumes is meant some considerable

the evolutionary relationships between extinct species‚ including megafauna and extant Australian species. Megafauna simply means large animals‚ in which most have become extinct within the last 20 000 to 50 000 years. The extinction of megafauna was‚ debatably‚ due to climate change and human expansion. Although‚ Africa still retains some megafauna‚ such as the elephant or the rhinoceros. Australia has managed to keep many examples of relict species‚ some from the time of the megafauna. These include

Reproductive Isolating Mechanisms In the 1940s‚ Ernst Mayr coined the term Biological Species Concept that was subsequently widely embraced by the scientific community. The definition stated that "Species are groups of actually or potentially interbreeding natural populations that are reproductively isolated from other such groups". Certain mechanisms are in place to prevent species from interbreeding with others and these are referred to as reproductive isolating mechanisms‚ which are biological

challenged Galen’s theories of the Human Body. This discovery had an impact on scientists. Vesalius’ discovery of the important differences between species also helped usher in the science of comparative anatomy‚ in which researchers studied animals to find their similarities and differences. In the process‚ they gradually began to recognize humans as being one species among many‚ with a few unique traits but many others shared in common with other animals. Some 300 years after Vesalius first shook off the

Any given environment will have a large number of niches‚ for example small variations in the temperature‚ humidity and exposure to sunlight will affect the ability of certain plants to grow and compete with other plants. Species that fit these niches will represent a very diverse population and therefore will
