The article “Rapid Evolution Changes Species in Real Time”‚ written by Jane Braxton Little‚ is a controversial look at evolution. This article presents a clear thesis‚ Little‚ along with scientist David Reznick‚ both believe that the process of evolution can be sped up. The process of evolution is due to environmental conflicts or possibly created by man. Throughout the article Little consistently focuses on her main thesis‚ and provides multiple examples to help back up her claims. Reznick states

this. A prime example would be the recent evolution of the wild Soay sheep residing on the Scottish island of Hirta. First of all‚ this changing environment is producing variations to this species in ways that evolutionists would not expect. In addition‚ the impact of these changes is widespread throughout this population‚ and will lead to many differences from previous populations of these sheep. Finally‚ the way the environment is affecting natural evolution of this species is different than many

The fault dictionary is constructed with the use of two evolutionary algorithms‚ i.e. gene expression programming and differential evolution. The presented diagnosis method has been verified with an exemplary circuit — a CMOS operational amplifier. I.

evolving due to advancements in technology and medicine. Even though humans have certainly gained more knowledge‚ there are still forces of evolution that cannot be stopped. These forces include; genetic drift‚ gene flow‚ and natural selection. Thus‚ by observing these principles in Darwin’s theory of evolution‚ it is reasonable to assume that the natural evolution of the human species will continue. Genetic drift is always occurring in

The first stage of Earth’s evolution was the precambrian stage‚ which is spread out into 3 eras. In order‚ they are the Hadean‚ Archean and Proterozoic eras. The Hadean Era lasted from when the Earth (and the rest of the solar system) formed 4‚550 million years ago to around 3‚800 million years ago. The simplest description for this era is Hades on Earth‚ because the earth at the time mainly consisted of liquid rock‚ almost endless volcano eruptions blowing our lava and boiling sulfur.

Introduction An experiment was done to determine the allele frequencies for a gene in a model population and to describe the affect of natural selection on this population. The Hardy-Weinburg theorem states that the gene pool of a non-evolving population remains constant over generation but the natural effect of Hardy-Weinburg’s equilibrium by selecting the individuals who are most fit for the environment‚ and allowing them to reproduce more of the genotype that is allowing them to survive.
