Natural Selection Darwin’s theory of natural selection states that species change over time through transmutation of species. The three necessary and sufficient conditions of natural selection are: Variation, Inheritance, and differential reproduction based on variation. There are variations between the individuals of the specific species, so the most fit and capable of surviving will be the one whose DNA will be replicated by its offspring. Because different individuals of the species have different DNA, one might have better genes in which will allow them to survive being hunted by predators and it allows them to carry the same genes and mutations to their offspring so they may also have a better chance of survival. This is called “survival of the fittest” which gives a certain individual a better chance of living a longer life and give birth to more offspring than another individual of the same species, because they may not have a specific mutation or gene. Both the version of a trait that an individual has, and the number of gene copies that individuals pass on to future generations help the species to thrive more in the future. The more offspring that an individual reproduces with the specific gene or mutation, the better chance that more individuals of that species can survive future generations. Natural selection is relevant to humans because it helps to give the species of Homo sapiens the best mutations possible in order for them to survive and pass their DNA off to offspring. An example where Natural Selection is important in humans is with our opposable thumbs and fingers. Over millions of years in time, our ancestors have carried that “opposable thumb” gene, so that every person living today has opposable thumbs, which has helped humans to grasp and use objects, such as food and utilities. The individuals that had the ability to use their thumbs and fingers were the ones to survive and pass their DNA off to their offspring. By passing this gene off to their offspring, it helps future generations with that specific mutation to help it survive off of and beat out any competitors and predators. A more recent and more specific example of this would be a disease such as The Plague, where millions of people died because they did not have the mutation that others had to survive the disease. Those people with the mutation in their DNA could pass it off to their offspring after all of the diseased died off. Example of natural selection; Skeletal adaptation Giraffes, lizards, and many other known species adapted to their environments through genetic changes to their skeletons. This form of natural selection meant that members of the population who didn't develop and present these skeletal changes died out. For example, giraffes developed long necks to reach food sources higher up in trees, so members of the giraffe population who didn't develop a long neck died out. At the same time, certain lizards in one region developed longer leg bones to help it climb up during periods of flood and to escape predators in the ground; shorter legged lizards of the same population died out until only the lizards with the long legs survived. Variation (micro-evolution) is part of Darwin’s theory of Natural Selection. Darwin concluded that Natural selection could only occur if there was variation in the population. Since then scientist have determined that Variation is caused by different genes, which result in different characteristics. They have also concluded that variation is an inherited thing. Since genes are inherited, so are the characteristics they carry.
