Evolutionary biology

One misconception of Darwinian evolutionary theory is that evolution is at a random chance. Natural selection is actually the stated opposite of random chance (Ryan p. 50). Although genetic drift and mutation play roles in evolution as causing chance events that result in a change in population, that does not mean that evolution as a whole is due to randomness. Natural selection is the greatest force of modern evolution, and is completed by the passing on of successful genes, not by random…

In Charles Darwin’s On the Origin of Species, Darwin identifies two different methods of adaptation that take place amongst organic species: natural and artificial selection. Instinctually, one may declare something as “natural” when it has not been tampered by direct human interference, and “artificial” when human intervention has changed the physical condition of that original characteristic. When comparing the two, many tend to favor the ease of efficiency that artificial selection has to…

The first was that organisms develop characteristics that are useful in a particular environment or lose traits that are not. He called this concept use and disuse, which is referred to as the “First Law”. Evolutionary improvements also happened by inheritance of acquired traits. Lamarck’s “Second Law” stated that adaptations to an environment could be passed on to the next generation to allow the entire population to benefit. This would therefore create new…

For Darwin’s theory of evolution there are where the questions of the diversity of life by evolution occurring, what was Darwin’s evidence of evolution and what Darwin didn't know about it. When did the the theory of evolution occur? What Darwin found out is about different type of living beings being able to survive and reproduce based on how well the species fits or don’t fit in the environment is by natural selection. For the species that survive and reproduce would be apart of survival of…

This poem’s main focus is to discuss the topic of natural selection. The author of this poem goes on to discuss how everything in this world is created by randomness, and biological need to change at the same time. That evolving is something that starts from simplicity, and ends in utter complexity. This poem also says that natural selection is something that happens out of necessity, yet it is a process that takes place without being able to control it. Everything in life begins as a simple…

An individual within a population with an advantageous trait is more likely to survive than the individual without that trait. This means the species without the advantageous trait have a higher chance of dying and will most likely reduce in number. If the trait is heritable, the individual with the trait will produce offspring with that trait and actively grow in number since the trait allows them to better survive in their environment. This is natural selection. Natural selection is the force…

Evolution says that organisms would change their type by natural selection but this is only happened in microevolution. I will explain what is microevolution? Microevolution is about that the variation among the species. With environment changing, some species would change their type to adapt environment. But no matter how they change, they are still same species. This is microevolution. Evolutionist only can verify microevolution is true. However, can evolutionists prove that macroevolution is…

How the Animal World Evolves Charles Darwin, in an excerpt from his book, On the Origin of Species by Means of Natural Selection, explains exactly how the animal world evolves. He brings together what he learned from years of research as a ship’s naturalist along the coast of South America to explain his scientific theory of natural selection and sexual selection. Darwin explains that if an organism has any deviation from its species normal traits, natural selection is the process through which…

Charles Darwin’s studies on natural selection showed how living organisms are unique but share similarities as well. His observations on the Galapagos finches were a prime example of unity and diversity of life. He concluded that the several species of finches derived from one common ancestor. Over time, the ancestral finches migrated to the other islands in the Galapagos and after many generations they gradually evolved differently to be able to adapt to their respective environments. He called…

Charles Darwin was a great scientist. He was one of the first to propose the theory of evolution.1 He also traveled around the world and learned about types of invertebrates.2 He has also studied medicine and written many books including The Origin of Species.2 These are just a few things about Charles Darwin that he has done in his life Charles Darwin has done a lot for the scientific world. Darwin came from a long line of scientists including his father and grandfather.2 When Darwin was only…
