Evolutionary biology

Since the beginning of time, people from all cultures, all religions and all regions of Mother Earth have contemplated and thought of how and why we came to existence. Some say reincarnation, some say God, some actually say aliens. (UFOSHOTSPOT.COM) But really, what it comes down to is something that most people can’t deny, the facts are evident. 46% of the American population believe in Evolution, “That poll found that a quarter of Americans believe humans and other species evolved "without…

Whitney Noonan 3/17/2016 Charles Darwin’s theory of evolution by natural selection was his way of explaining adaptation and speciation. This theory gave a reason as to why species “change” over time and explained the process. This was a huge discovery for Darwin because now we know that species are not fixed and are changing. Ethology, the study of animals in their natural environments, also played a role in the development of Darwin’s theory. Konrad Lorenz’s geese imprinting experiment…

life refers to the gradual development of various organisms to adapt and better adjust to their current environment, originating from a common ancestor, while the origin of life is a more complex question. The author the initiates to explain the evolutionary perspective on the subject, which is mostly unbiased and informative. Evolutionist theorise that physical existence in our planet arose from solely natural means, for this reason many believe that it would be unreasonable to even conceive…

Evolutionary theory has been a widely questioned theory since it was put into the science world as an accepted theory. One of the trailblazers in this theory is Charles Darwin. He is famous for being a founding father of evolutionary theory and much of what he theorized is still accepted within modern science. There are a few parts of his evolutionary theory that are different than what modern scientists think. Darwin’s theory, though, is still sought after by many in the evolutionary field…

Speciation is a process in which organisms within a population evolve to become a new species over time. Charles Darwin believed that eventually a single species will split off into two different populations, becoming two new species. Some of the speciation modes are allopatric and sympatric, and polyploidy is a mechanism of speciation. Allopatric Speciation Allopatric speciation is a common mode of speciation in which a population of a single species becomes divided, geographically isolating…

Sri Aurobindo is one of the gifted philosophers of the Indian sub-continent. He had a thorough western upbringing and education. He understood evolution as Darwin. He points out the story of evolution would ultimately leave your life empty. Sri Aurobindo believes science offers rationality. He argues there is more to life than simple biological longevity and spending time to control life. Sri Aurobindo felt that the human being is a being of aspiration. Sri Aurobindo feels just as the material…

Evolution is how modern living organisms are related to ancient ones. Organisms have diversified and modified through ages and old one became extinct. According to Charles Darwin, all species have common ancestors. This means that, for instance, whales and dogs are related to each other by an old ancestor. Indeed, many organisms have common traits and characteristics, but this still doesn't mean that they are related. Darwin's theory, which all organisms descend from one ancestor, is the result…

Alfred Russel Wallace and Charles Darwin were once friends, contemporaries, and rivals. Both scientists proposed the theory of natural selection, the process where organisms develop traits over time that adapt to their surrounding environments and become more common through reproduction. Darwin published his work On the Origin of Species detailing his theory of natural selection in 1859, while Wallace had discussed with Darwin the theory as well. The theory of natural selection led Darwin and…

an obscure character in evolutionary history. Lamarck was appointed professor of invertebrates. In that moment, there was few study on insects. He wrote a series of books about invertebrate zoology and paleontology. Though other scientists in his day hinted at the possibility of evolution, Lamarck declared it forthright. He was discredited by his peers and died a poor man. However, Charles Darwin and others respected his as a great zoologist and the forerunner of evolutionary theory. Georges…

Charles Darwin was the father of the revolutionary theory called evolution. This theory stated that species would would adapt to their environment by slow changing the species through millions of generations. To prove this theory Darwin examined animals from different island in the galapagos islands. One of his more well known observations is his observation of the galapagos finches. When Darwin observed the finches he realized they were all similar but some had different wing colors or…
