Evolutionary history of life

biological history of earth. Benton (1995) talked about how mass extinction drives diversification in the biological community, Erwin (2001) discussed on how species recovery occurs after mass extinction and Barnosky et al. (2011) talked about the possibility of future mass extinction based on the comparison between the present and past extinction data. According to Benton (1995), the massive diversification of life from a single common ancestor is well known throughout the history of…

years to form. Also, that life on the planet has come about by the process of evolution, as proposed by Charles Darwin. Scientists study the results of old processes in the present and try to reconstruct…

Moving into the new millennium, the field of medicine has a history that has allowed it to grow to what we see now in the modern day. Different advancement in evolutionary biology, biomedical science and/or medical technology has allowed physicians to better diagnose and treat their patients since the beginning of the professional practice of medicine. Evolutionary biology has allowed medical practitioners and public health specialists the understanding of the physiological basis of how diseases…

example the appendix a rather useless organ but at one point throughout human history it was summarized that the appendix played a crucial role in digesting fibers and cellulose…

generations, people have questioned the origin of the human species and how we came about. Until the 19th century, people had no scientific clue as to how humans came to be the walking, talking, intelligent species we are today. With the introduction of evolutionary theory by Charles Darwin, we finally have an idea of how we evolved over many generations to become the species we are. Some people in today’s society are opposed to the theory, mainly being misinformed on what it actually means.…

organisms . They are thought to have developed and diversified from earlier forms during the history of life on earth . Evolution is also the development of something from a simple complex form . It is change in the heritable traits of biological populations over successive generations . For example the closest thing to a human is a chimpanzee . Fossil Record is one examples of evolution it is life's evolutionary epic that unfolded over four billion years ago . It has environmental conditions…

product of nurture. He argues that rape is mainly caused by societal and cultural upbringing. On the other side, Randy Thornhill and Craig T. Palmer, authors of “Why Men Rape”, argue that nature is the main cause of rape. They believe that rape is an evolutionary adaptation. Although both “Sex Crimes I: Rape and Sexual Assault” and “Why Men Rape” have similar views discussing high rape rates, the articles differ vastly in determining the specific nature or nurture aspects of rape, for example,…

There has been much thought in the scientific community about the polymorphism of human blood types and their genetic factors, and disagreement and uncertainty about details like which evolutionary mechanism blood types have followed over the course of their development and how one’s blood type and environment interact. Investigation and study of blood types has revealed many aspects in which certain blood types provide some advantage to their possessors, providing evidence that they were…

by certain biologist’s who argue evolution favours the directional development of complex life . However, life is not a straightforward progression towards complexity. Natural selection can’t explain revolutionary change because while species produce evolutionary trends through their adaptive challenges, there are random events such as mass extinctions that dramatically alter the progress of life. Life on earth emerged from a series of fortuitous accidents. The distance of the Earth from…

psychopathology, or using the biopsychosocial model in general (Schore 2007). History John Bowlby is known as the “father of modern attachment theory” (Brandell 2007). In the 1930’s John Bowlby worked as a psychiatrist in the Child Guidance Clinic in London, where he treated many emotionally disturbed children. This experience led Bowlby to consider the importance of…
