Natural selection forms the foundation of how we understand the ways that species have formed over time. Another form of selection is sexual selection‚ which is the selection of traits based on their roles in courting and mating. It involves attracting a mate with the greatest fitness while simultaneously portraying oneself as the best mate for selection. Fitness‚ described in natural selection‚ is the ability to reproduce and leave successful offspring that will continue the cycle. Sexual selection

The theory of evolution by natural selection‚ first formulated in Darwin’s book “On the Origin of Species” in 1859‚ is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Scientists‚ and other professionals hold a large range of positions about religion and the act of supernatural forces or entities in the universe. Evolution is one of the best theories‚ because it is supported by evidence. There is two main points in evolution‚ which

What is the difference between artificial selection and natural selection? (Give an example for both.) The key word in these processes is selection; when we have several clearly different options to decide upon‚ we look at the option we believe serves according to our best interest and “cull” the others. Artificial selection is the process of humans selecting certain phenotypes in organisms to serve their purpose. An example of artificial selection can be observed in the phenotypic diversity of

States has become heavily reliant on using nonrenewable resources. The excessive uses of these resources‚ such as coal‚ are extremely harmful to the environment and can be considered responsible for global climate change and the destruction of a once healthy atmosphere. Some companies have claimed to find a “clean” source of energy called natural gas‚ found deep within the Earth’s crust. Commercials created by these companies state that natural gas is easy retrieve‚ cheap and clean burning. However

On this voyage‚ Darwin studied and collected information on various species from around the world‚ allowing him to develop his Theory of Natural Selection. Darwin’s Theory of Natural Selection suggests that organisms that are best suited for their environment will survive and produce offspring. In more basic terms‚ it means that natural selection is essentially

measured by the ability of an organism to survive and reproduce in an environment. Charles Darwin’s explanation of natural selection involves three principles. The first principle is variation which states that every species is composed of a great variety of individuals. Some of these individuals have adapted to their environment than others have. The second principle of natural selection is heritability. This is where offspring inherit traits from their parents in some degree or another. The
