things come to mind such as climate change‚ water pollution‚ species loss‚ or deforestation. Yet so many other problems get overlooked because they are unrecognizable or do not get as much media coverage. One of these issues is the threat of invasive species. Some people will walk past them every day without even realizing it. After all why would anyone question something that looks just like another plant‚ insect‚ or animal. Invasive species are not as in your face as pollution or deforestation‚ but

suggested to demonstrate the gradual transition from one species to another through a multitude of changes. In essence‚ the transitional fossils are the remains of the species that have gone extinct‚ and these species are represented on the phylogenetic tree. As reportedly most species go extinct‚ finding fossilised remains of them is virtually the only way of proving their one-time existence. However‚ only a very tiny fraction of species fossilise and can be found in fossil

concept - which‚ granted‚ is a big one. Biodiversity: Life‚ the world‚ the variation of life for the entire globe. It’s a big idea with a long history. Biodiversity found on Earth today consists of many millions of distinct biological species‚ the product of four billion years of evolution. But the word “Biodiversity” itself is actually quite new. "Biodiversity" was coined as a contraction of "biological diversity" in 1985. Clever eh? And as politicians‚ scientists‚ and conservationists

sub-family Papilionaceae and family Leguminoseae. The genus Cicer encompasses 43 species. Among them nine are annuals‚ 33 are perennial and one with unspecified life cycle. Of the 9 annual species‚ Cicer arietinum L. is the only cultivated species. Based on the morphological characteristics‚ life cycle and geographical distribution‚ Van der Maesen (1987) classified the Cicer genus into four sections. Eight annual species‚ namely C. arietinum‚ C. reticulatum‚ C. echinospermum‚ C. pinnatifidum‚ C. bijugum

In The Descent of Man Darwin argues whether humans are one species or if the races of the world make up their own respective species. Darwin considers both the differences and similarities between races‚ and using both biological and social observations‚ he concludes that the different races put together make up one species--homo sepiens. When determining whether the separate races make up one species or not‚ Darwin

that all organisms are made by God in their current state and require no additional modification. As a result‚ many scientists in the 1700s explained that an organism’s compatibility to its environment is because of the principle that God created a species to suit a specific environment. Contrary to the beliefs of early philosophers and scientists‚ an organism’s compatibility to its environment is caused by natural selection. Natural selection‚ the process in which individuals with certain heritable

We dump all types of waste into our rivers and seas‚ doing irreparable damage to freshwater and marine species. We hunt for sport and use animal parts to cater to our exotic tastes. All our actions are resulting in the dwindling of wildlife. We are losing plant and animal species at an accelerated rate. Ladies and gentlemen‚ what can we do to stop this massacre
