Evolutionary biology

'Lamarck and Darwin were naturalists who theorised the evolution of species' characteristics. They arrived at some common conclusions, but also differed in certain important respects. We can illustrate their similarities and differences by considering the nature o Lamarck’s theory in relation to the evolution of species characteristics to explain the relationship that exists between a living being and the environment they live in. Through his observations, he observed that if a living being is…

Heredity and Evolutionary Theory Charles Darwin, a naturalist and geologist held the belief that all living things share a common ancestor. This statement is in relation to his contributed Theory of Evolution that has greatly impacted the world’s view about the human originates. Evolution is defined as change over time 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…

As human, we often ask ourselves: where do we come from? Through time, we have tried to answer this question, usually with religious beliefs. However, some people also had their own theory. One of the most known is the theory of evolution and natural selection by Darwin. But, what are natural selection and evolution? Those concepts are often misunderstood. Few people know their different process, the origin of natural selection and the evidence of evolution that we have found. In the first…

'process of natural selection'. The theory of survival of the fittest stated that, the best physical specieman of the species and only those in the best shape and health will survive. And the theory of the process of natural selection stated that, evolutionary change occurs through variation between individuals. Charles Darwin's theories was soon applied to humans and called 'Social Darwinism' and 'Scientific Racism' developed.…

Since the publication of Darwin’s “On the Origin of Species” in 1859, natural selection has been widely accepted by the scientific community as the engine that drives evolution, or the change of frequency of heritable characteristics in a population over time. Natural selection results in the survival of the fitter individuals of a given population, and therefore the increase in frequency of the genes that produced the adaptive phenotype. For natural selection to occur, there are three…

disregarding a “God” that was a part of creating living plants and animals. In October 2004, the Dover Area School District located in York County, Pennsylvania, required biology classes to teach intelligent design along with the theory…

The Theory of Evolution, conducted by Charles Darwin brought a grateful amount of controversy in the science and education fields today. Debates between is Darwin’s evolution theory correct and if it should be taught in schools. Many disagree that Darwin’s theory should be taught in public schools because it is not proven and it’s a religious belief. Yet Darwin’s theory has all the characteristics of applying to science education. Teaching evolution in public schools wouldn’t change one’s morals…

Charles Darwin was a prolific and monumental figure in biology and modern science as a whole. Through his theory of evolution most of the current knowledge of biology is derived. Throughout the chapters X, XI, XII, and XIV of The Origin of Species Darwin argues that there is a mechanism that drives an evolution of species and that species inherently transform and mutate over long periods of time. Darwin argues that species have mechanisms and methods that modify them over long periods of time…

The four forces of evolution are mutation, natural selection, genetic drift, and gene flow. Mutations are the only force that can change the genetic code and without them the other forces wouldn’t happen. When a mutation takes place in a sex cell, it can them be passed down through generations. Natural selection was first brought about by Charles Darwin. It is the belief that the better an organism adapts to their environment, the more likely they are to live longer as well as reproduce. Genetic…

Charles Darwin and Jean-Baptiste Lamarck were two most influential theorists who both lived in the 19th century. The two naturalists, Darwin and Lamarck, produced a theory of evolution which both had definite similarities and differences. The term, ‘evolution,’ is how different types of organisms are developed over generations. Jean-Baptiste Lamarck was a French biologist (1744 – 1829) who created his theory based on Lamarckism, which is his idea when an organism can pass on characteristic that…
