Sexual selection

biological evolution, natural selection and descent with modification. Over many generations and an extended period of time the genetic change of an organism is bound to happen, these changes are called biological evolution. Scientists have studied these changes and how they occur for many years, all starting with Charles Darwin on the Galapagos Islands.…

Richard Dawkins is a well-known biologist and a writer who takes after Charles Darwin. Charles Darwin was the man who originally discovered the possibility of natural selection. Scott LaFee is a science writer who believes that Dawkin’s work proves that he is very similar to Charles Darwin. “Richard Dawkins, the 68-year-old English biologist and best-selling author, whose rousing defense and explanations of evolution have earned him international admiration, the enduring enmity of creationists…

the mosaic concept to prove that molecule ancestors were likely present in different organism at different times. Gene drift is one of the major players in evolution. Gradual change in the genome of population over time, without Natural Selection. Natural Selection works on mutations which impact survival, favoring those which enhance the chances of survival. When DNA sequence appears in the genes, it has the same effect as mutations-nature can select for or against it resulting in evolution.…

and according to Darwin, this process of which all diverse kinds of living organisms have developed into their own branches is due to natural selection which grants the organism to better adapt to their environment in order to survive and reproduce for future generations through the passing of their fit genes. These adaptations occur when natural selection favors a specific heritable physical or behavioral trait that have been…

The Theory of Evolution states that all life on this planet, myself, a tree, or a dog, descend from a common ancestor that underwent physical changes through a process called natural selection. This process takes millions of years to occur and directly challenges the book of Genesis and the belief that the Earth is 6,000 years old instead of being 4 billion. In the United States many conservatives deny evolution and some have gone so far…

Almost all religions have some set of morals. These morals make us who we are even at the deepest of levels that we can’t even access. This also means that anyone who goes against these morals is typically shunned in many religions. There are many religions that look at this as a chance to pray for forgiveness and to become closer with whom they believe in. Religious groups always want to add new members to the group and they look at this as an altruistic act because they believe they are…

Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the…

had been and is currently abundant in farming, as the fittest animals were selected and bred, this created a larger stock of the further useful domesticated animals and were continuously bred for that specific trait. This was known as conscious selection; however, varying traits in domesticated species were also unconsciously selected. This meant that certain traits or…

When Charles Darwin published his famous book “On the Origin of Species” (1859) it outlined what he had learned on his geological exploration around the world. Darwin’s theory of evolution states that natural selection (the process whereby organisms better adapted to their environment tend to survive and produce more offspring) is the cause of evolution. Through many explorations, his findings supported this claim. For example, when he traveled to the Galapagos Islands in Ecuador, he observed…

During 1850 -1900, the question about the relationship between human and nature was continuously examined by Darwin, Wallace, and Forbes. Charles Darwin with his theory “natural selection” has tracked down the origin of species. His theory was based on the idea of “struggle for existence”. In his document, he said: “the term Struggle for Existence in a large and metaphorical sense, including dependence of one being on another, and including not only the life of individual but success in leaving…
