Essays on Natural Selection

In biology, the theory of evolution doesn’t exactly tell us how life began on Earth, but tells us how life, once it came into existence, diversified into the many incredible forms we see now and in the fossil record. It also helps us make sense of the way in which modern creatures continue to adapt…

Many millions of years the planet was dominated by lizards great and small. It was a place ruled by the laws of natural selection where the only way to survive was to be able to defend yourself with what you had. It was a constant struggle for food, shelter, and supremacy. It was about survival…

Charles Darwin was a famous scientist whose most famous studies were the evolution of man and all other creatures. Darwin realized that certain species became extinct because they were not both strong physically and mentally, and he explains his theory which is called natural selection, and later claimed the phrase “Survival of the fittest. ”…

What lands and observations inspired Darwin to develop his theory of evolution? Driven started by studying with proclaimed geologists learning how to map lands and animals and develop theories. Darning’s observations in the lands of Wales and throughout various places in South America lead to his theories of coral reefs and formation of volcanic islands…

Darwin envisioned natural selection acting so slowly that its effects would be imperceptible in a human lifetime. But in the late 1900s, evolutionary biologists began to detect small but significant changes taking place in a handful of species. In the past decade, many more cases of natural selection have come to light, and scientists now…

Natural Selection The article “Natural Selection: Charles Darwin and Alfred Russel Wallace” discusses the emergence of natural selection theory, its implication and details. Firstly, the article describes pre-Darwinian ideas about evolution claiming that it is Darwin who was the firs to show the evolution of species and to offer “a plausible mechanism by which life…

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population, and…

Natural selection relies upon the assumption that all organisms produce more offspring than can survive in an environment demonstration limited resources. In this lab, we are trying to see which prey (beans) would survive and which predators (students with different type of mouthpart) would survive. I think green bean would survive because it is very…

The species I will be discussing is Alopex lagopus whose common name is Arctic fox. The Arctic foxes are located in the Arctic region and they live in the areas around the North Pole which is characterized by long durations of snow cover (Blix, 2005). The trait I will be discussing is fur coloration. The…

What is a gene?According to the national institute for health and ‘TheBody. com” a gene is a unit of heredity.  The gene represents the smallest collection of DNA that can be demonstrated to transmit characteristics (traits)  to an organism’s offspring.Both sites are well established bodies involved in the science of physiology and health fields dealing…
