Obesity is the major problem and it causes strain on the arteries and clogs can happen to lead to heart disease. In addition, with type 2 dia...

Speciation and evolution work together to create patterns that one can observe and understand. The speed of speciation is also a concept that can be studied because of its various components that play into the idea. Speciation in simple terms is the formation of new species in the course of evolution that are unique and distinct. Organisms can adapt and become new species in certain cases and time is a variable we can study here. Organisms can evolve new traits that allow them to thrive better in a specific environment. When looking at how long it takes for new species to form, the answer is not simple. There are contributing factors just like anything with evolution. An intense environmental pressure may increase the rate at which new species evolve because they must adapt quickly. This could be seen in R this week because the toxic waters required the fish to adapt or die. But other factors are also at play here too, sexual selection and gestation periods. An elephant can not procrea...
