A change in the lake’s temperature or chemistry may affect a food source for a certain type of fish. This type of fish may die out and leave the lake with one less species in it. The loss of one fish or food source may impact other populations and furthe diminish species diversity. Cause Invasive Species - plants

vital to the ultimate survival of a species. Diversity ensures that the species is immune to specific genetic complications‚ infectious diseases and other serious health concerns. It also guarantees that the species independently and as a whole can adapt to changes in their environment and can survive and live prosperously. According to researchers genetic diversity occurred more than ten thousand years ago when extreme climatic changes drove many animal species to extinction. The cheetah today is

The transfer of genetic information is not limited by species‚ kingdom or even domain and can occur between species that are very different. Within the kingdom of Bacteria HGT has been observed to function in three ways. The first is referred to as bacterial transformation and is caused by the alteration of a cell‚ which results

Our intelligence to create tools and technology is another unique trait that separates us from other species‚ also our capability to adapt and change to different types of climate so that we can survive. The fact on how we look and act that differentiates us from other species gives a clear observation on what makes us human externally. Internally we have our brains and body type that show we are human‚ even though

evidence for evolution? Which provides the weakest argument for evolution? Fossil records are etched in stone and prove that all life began somewhere and shows a timeline of the origin of new physical features. From fossil records you can gather when a species occurred‚ how they looked‚ what they ate‚ where they lived and many other forms of data which can not otherwise be gathered. I believe that this is the best way to provide evidence for evolution because it is basically documentation in stone and nothing

The movement of human species continued towards India. It took further research to understand how they got there‚ but findings show that 70-50‚000 years ago the ice caps were expanding creating more deserts and allowing them to walk through. The same process was followed in India‚ and Tamil Nadu was discovered to carry the gene of the past. The white chromosome in male is the evidence of the past because it is the only one that does not change. After India‚ the species continued their route towards

fact that species have been saved or reintroduced as a result of captive breeding shows their value.” Additionally‚ this shows that the conservation of animals is valuable because so many species have been saved through these programs.

Understanding Evolution: A Simple and Easy Illustration by Adam Chandler on Saturday‚ June 23‚ 2012 at 5:54am Many people don’t understand what evolution is‚ and how it happens. Therefore‚ some of them might reject it based on not knowing what it is‚ or based on a wrong understanding of it. Because of that‚ I find it my duty to make an easy to understand illustration of evolution‚ as I believe I understand it well. I’ll try to make this illustration as easy as possible‚ and in many places‚ oversimplified
