Discoveries in the Red Queen Hypothesis and Evolutionary Arms Race

Researchers have lent credibility to the concept of an evolutionary arms race. Charles Marshall, a biology professor and the director of the UC Berkeley Museum of Paleontology, states, “ But we found that a decrease in the origin of new species is just as important as increased extinction rate in driving mammals to extinction.” (UC Berkely News Center, 2013) Their findings help highlight the concept that diversity loss of species is a sign that the environment has overwhelmed them. This hypothesis was originally developed by Leigh van Valen who indicated that the probability of a species survival was based in its competitive abilities with the environment. The environment in this case is other species as well as the life sustaining resources like food and water. As species reproduces, they create opportunities to develop stronger adaptations (new forms) that are better aligned to environmental threats. Generally, the more a species reproduces the more successful it will b
