Possíveis influências astronômicas na evolução - das espécies biológicas
Abstract
The traditional darwinian view has it that organisms evolve and beco me extinct primarily as a result of competitive interactions, with changes in the physical environment being of subordinate importance. However, what caused the mass extinction events remains a contentious issue of enduring fascination, as witnessed by a clutch of papers in the last years.
Our goal in this work is to present and discuss the pros and contras about the physical evidences for an unusual event at the time of the mass extinctions. Also, we present the suggestions that the disappearence of species from the surface of the Earth has been periodic and stimulated contradictory explanations and also a diversity of ways of dealing with information available at this momento
