The fifth part of the evolution theory is natural selection. Natural selection is an idea that life doesn’t require creation or guidance from a supernatural being. Natural selection depends only on nature in which the population will adapt to their environment while the one who are unable to adapt will die off. But natural selection cannot provide perfection but can only help the creatures to evolve just enough to be able to survive.

11. Define the following: Genetic drift: unpredictable fluctuations in allele frequencies, reduces genetic variation over time through such losses of alleles

Evolution: the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

Evolution: A heritable change in the characteristics within a population from one generation to the next; the development of new types of organisms from preexisting types of organisms over

Evolution - a change in the number of times specific genes that codes for specific characteristics occur within an interbreeding population over a period of time.

Evolutionary biology: the study of the origins and changes in the diversity of life over time 6. Genetics: the study

Evolution: Charles Darwin's theory was that species change over time, or evolve, in response to their environment. A good example of this is the evolution of the Kangaroo. Approximately 55 MYA the kangaroos looked quite similar to a possum and it was a tree dweller with a prehensile tail, but as Gondwana split up, the rainforests disappeared, the climate became hotter and the land dry and arid, the kangaroo evolved along the way and have come to look like what they do now.

To illustrate, the theory of evolution by natural selection is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Darwin was the first to formulate the theory and alludes to the fact that given enough time and enough accumulated changes, natural selection can create an

1. Evolutionary theory describes how populations change over time due to changes in the gene pool. There are several mechanisms that can change a gene pool and allow evolution to occur. Natural selection, mutation, gene flow and genetic drift are some of the driving forces behind evolutionary change. Natural selection and genetic drift are the mechanisms that decrease genetic variation, whereas gene flow and mutation are the driving mechanism to increase genetic variation. Natural selection is basically the understanding that the environment can not support unlimited population growth, and not all organisms are able to reproduce to their full potential due to trait variation. For example, a black fly may

Variation- it offer variety of different characteristics feature which allows certain species to become resistant/immune/protected from certain environmental factors(predators, diseases) also leading to better survival chances which increase rate of

The descendants of the species have been given changes from their ancestors. This is called natural selection. Natural selection is a type of evolution that animals go through when there is a hardship in their natural habitat. Most animals go through natural selection to survive, they can pass it on to their kin.

The formal “Theory of Evolution” thought to have come about by Charles Darwin, is built on the premise that all life is related and has descended from a common ancestor; meaning the birds and the bananas, the fishes and the flowers are all related (“Darwin’s Theory of Evolution”). In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival. This process is formally known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different

“If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing environment” (O’Neil, 1998-2013). Scientists call this reproductive success. “Within a specific environment context, one genotype will be better than another genotype in survival or reproduction for certain reasons having to do with the way its particular features relate to the environment or relate to other organisms within the population” (Futuyma, 2000-2014). The theory of evolution is explicable through various kinds of scientific research.

Convergent Evolution is the process where an unrelated or distantly related organism develops similar characteristics in order to adapt to the same environment. When the time passes this adaptations made by the organism makes the species to add up similar favorable traits in very different species.

Evolution refers to change over time as species modifies and separate to produce several offspring species.
