Microevoluon is “the theory that natural selecon can‚ over me‚ take an organism and transform it into a more specialized species of that organism‚ whereas macroevoluon is “ the hypothesis

Natural selection and speciation are two examples of how biodiversity can be expanded within an ecosystem. Natural selection is the process by which characteristics are inherited to enhance survival and increase the chances of reproduction in future generations than those that do not‚ altering the genes of a population over time. These characteristics will help future individuals within the population to become more efficient and better suited to their environment. Speciation is the process by which

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

That man is Charles Darwin‚ a British born naturalist and geologist‚ who created the theories of Evolution and Natural Selection. Out of the two theories‚ Evolution has sparked the most debate out of various Religious communities all over the world. Evolution is defined by Merriam Webster as “descent with modification from preexisting species: cumulative inherited change in

of natural selection are Darwin’s finches and Toxic Cane toads. Bigger birds promptly began eating all the larger seeds‚ pushing the smaller finches to specialize on smaller seeds. So‚ the beaks of the finches changed depending on their food source. Secondly‚ toads with long and strong legs have been rewarded. Toads with shorter legs have to stay behind. In this case‚ nature selects the longer-legged toads. These two species of animals show how natural selection occurs. Natural selection causes evolution

His smooth and fluent style‚ helps the reader gracefully follow along. Though his findings inspired many scientists to scientifically analyze his claims‚ Darwin’s studies were not with in the realm of science. Rather‚ his findings are logical which he found by studying various species among the natural world over a long period of time. The use of constant examples

Charles Darwin’s theory of evolution puts forward a statement‚ ‘Survival of the fittest’. This is widely considered true‚ but in reality truth is a slight variation of this‚ more commonly known as natural selection. The survivors are the ones who adapt best to their environment and are then able to reproduce. This means that there genes carry on through the generations and we gradually see the preferred characteristics for survival become more common. Over time the human race will become more and

suggested that species evolve through sexual selection which involves attracting the mate with the greatest fitness and at the same time maximizing the chances of being selected as ‘fit’ themselves. Fitness‚ in the context of the evolutionary theory‚ means the ability to reproduce and have offspring‚ making it more likely for them to pass on their genes to the next generation. To explain this‚ Darwin came up with the two processes: Intra-sexual selection refers to the evolutionary process where members

Discuss the relationship between sexual selection and human reproductive behaviour. (24) Sexual selection can be used to explain certain characteristics or behaviours which increase an individual’s reproductive success. These characteristics may get exaggerated over evolutionary time. In humans‚ these characteristics may include good physical and mental health‚ as well as physical features such as good looks etc. these characteristics are attractive because they show an ability to reproduce and
