Charles Darwin and Alfred Russel Wallace's theory explains how evolution occurs. Individuals naturally vary in traits in a population. With limited resources, competition exists in which those better adapted - with beneficial traits suited to the environment - are more likely to obtain resources, survive, reproduce, and pass traits to offspring over successive generations. This natural selection of advantageous traits leads species to evolve over time.

Earlier this month, an online petition voicing scientific opposition to Charles Darwin’s theory of evolution reached more than 1,000 signatures, pointing to an increased consensus among the scientific community.

The theory of evolution comes into question with William LePar’s spiritual source, The Council, and a researcher. Questioner: With the specific exception of man and his influences on nature, can the basic idea of the theory of evolution that species have continued to develop through time to adapt to the conditions around them, can that be generally accepted?

Only a few smaller representatives of the megafauna remain, such as African elephants, rhinoceroses, and hippopotamuses. Scientists are skeptical as to whether the warming climate is to blame for the extinction at the end of the last ice age or the fact that modern humans were beginning to rapidly spread around the globe and hunt these…
