Evolution

Evolution is a change in allele frequency in a population over time. This is the passing of genes from one parent to children. This is not the same thought process that people lean toward. People tend to think of evolution as people evolving from monkeys over time. It is a change in a species over time. Evolution is a change in allele of species over time. An individual carries multiple traits from their parents allowing them to pass these genetics down to their children. This is the theory of…

Ammonites are an extinct marine mollusc animal. They are successful and unsuccessful over their duration of evolution. Their shells prove to be a successful part of their evolution because it gave them the ability to be protected from predators. Also, their shells helped them to travel around and expand for better survival. The asteroid is the unsuccessful part of their evolution, since it just completely obliterated the ammonite species as a whole . 6. The Biosphere 2 was significant in…

Evolution is the theory that all living forms came from ancient ancestor as well as the change in the heritable characteristics of biological populations over successive generations. (Metz 2017). Through the series of changes, genetic drift, migration, and natural selection today’s descendants show an amazing amount of similarities as well as differences. According to the journal article development on a tiny scale is named microevolution, relating to the changes that happen such as insects…

One misconception of Darwinian evolutionary theory is that evolution is at a random chance. Natural selection is actually the stated opposite of random chance (Ryan p. 50). Although genetic drift and mutation play roles in evolution as causing chance events that result in a change in population, that does not mean that evolution as a whole is due to randomness. Natural selection is the greatest force of modern evolution, and is completed by the passing on of successful genes, not by random…

known for the age of scientists and philosophers that flourished and spread their ideas throughout Western civilization. One of the most prominent scientists of the time was Charles Darwin, who introduced his theory of evolution and natural selection in 1859. The theory of evolution spread like wildfire throughout intellectual groups, and from that theory branched many other social theories. The main theory that came about from Darwin’s was Social Darwinism, which dominated Western thought and…

anatomy refers to the study of anatomical similarities and variations in different species. It provides important evidentiary support for evolution and natural selection as similarities can be an indicator that certain species share a common ancestor. There are two main types of comparative…

Evolution is an idea that has been toyed with by many other scientists for centuries, but is generally considered to be the “unifying theme” and the “binding force of all biological research” (Evolution: Theory and Science). Georges Cuvier and Jean-Baptiste Lemarck both had theories that kind of headed towards evolution, but they simply had pieces of the whole picture. The writings and theories of these two naturalists and others are what inspired Darwin on his travels. All this along with his…

In 1925, the Scopes Trial occurred because John Scopes, a high school teacher, was accused of breaking Tennessee’s law against the teaching of evolution in public schools. The prosecution welcomed William Jennings Bryan to take part in the trial, while the defense chose Clarence Darrow on their team. Bryan was a firm religious fundamentalist, however encouraged the indictment to battle its fight on sacred grounds. Bryan trusted that groups were legitimized in setting educational principles…

or most of its original functions in the course of evolution, such as human appendix. B) For example the picture above clearly shows you the examples of Vestigial Structures are included in the human appendix, the pelvic bone of a snake, and wings of flightless birds. C) The evolution of the Vestigial Structures is homologous to structures that are functioning normally in other species. Therefore they are considered evidence for evolution, which can be beneficial heritable traits, will…

common ancestor of both species (Lalueza-Fox et al. 2008). Focusing more on the human lineage, other alleles resulting in the O blood type emerged at least three times in the course of human evolution and were found to have changed over time due to recombination and selection, providing evidence that neutral evolution was not the factor that increased the frequency of blood group alleles and blood types (Calafell et al. 2008). The hypothesis that balancing selection has occurred on the blood…
