Traditional textbook discussions of ancestral descent are ‘a festering mass of unsupported assertions’.
A recent study conducted by Ph.D student Sarda Sahney, et al., at the University of Bristol, published in Biology Letters, used fossil evidence as a basis for analyzing evolutionary patterns over 400 million years of history. Sarda Sahney and colleagues posit that the availability of “living space” rather than competition for survival — as Darwin proposed — is the governing factor behind the evolution of species. Their theory is based on the concept that the process of evolution in which an organism is involved is highly influenced by its “ecological niche,” which includes such factors as food resources and habitat conditions. According to the study, large evolutionary changes occur in animals as a result of their migration into living spaces which are unoccupied by other animals.
Former president of Gonzaga University and noted scholar Fr. Robert Spitzer confirmed that “Darwin assumed that competition was what was driving the development of human species and particularly the dominance of one species over another.” Fr. Spitzer pointed out that “there is no way of reaching back in time and finding empirical evidence of that fact.” [Read more…]
