The giraffe is one of only two living species of the family Giraffidae‚ the other being the okapi. The family was once much more extensive‚ with over 10 fossil genera described. Giraffids first arose 8 million years ago (mya) in south-central Europe during the Miocene epoch. The superfamily Giraffoidea‚ together with the family Antilocapridae (whose only extant species is the pronghorn)‚ evolved from the extinct family Palaeomerycidae.[9] The earliest known giraffid was the deer-like Climacoceras

The Pleistocene period was a time when ecological changes emerged. During this period glacier formations began to arise and have been accredited with playing a role in the divergence of different species. For different species of avian there has been controversy between their origins and speciation events. Studies have been conducted for this controversy to try and find which theory to accept for the songbirds. Even though a majority of studies have accepted Late Pleistocene events role in the speciation

This collage gathers all these man-made animals‚ with different colors and species of animals mixed together and creates a strong visual impact on the audience. The eccentricity of combinations and the arbitrary splices between two very different animals all represent the unnatural essence of these creatures. The rakunk and the

will bring new alleles to the population that were not there before; but could also exist in other species of the same gene pool. Alleles come from mutations since the beginning of time. They have been introduced and have changed the genetic makeup of the population over and over again‚ and have been passed on from one to another. These mutations can sometimes be harmful to the species‚ but the species will change and adapt to these mutations. New alleles are not created during sexual reproduction

Lord of the Ants Ed Wilson Was hit in the eye by the dorsal fin of a Pin fish and went partially blind‚ so he turned his interest to animals small enough for him to see entirely and up close‚ something small enough for him to hold between his thumb and pointer finger to inspect.

We will discuss the reasons for longevity in the evolvement of the human species. Diamond addresses through chapter seven‚ how aging and menopause are strongly connected to longevity. Men and women have been tested in various different ways to solve the mystery behind the theory that reproduction is the cause of post-generative

other species – the White-tailed Eagle and Red Kite – have had some help from conservationists and are now also doing rather well. Formal classification: Carl Linnaeus (23 May 1707 – 10 January 1778) was a Swedish botanist‚ physician‚ and zoologist‚ who laid the foundations for the modern scheme of binomial nomenclature. He is known as the father of modern taxonomy‚ and is also considered one of the fathers of modern ecology. Binomial nomenclature is the formal system of naming species. The essence

Mullets and Catfish are the major brackish water fish‚ which have supported sustenance fishing for the lake fishermen. The highest concentrations of flamingo are found in the periphery of the lagoon where the water level

Adaptive introgression has proven to have many adaptive values and affects the genomic variation of humans and many other species. Many populations display examples of introgression. In the article prof. Haws and Cochran talk about introgression and how it affects it affects genomic variation among humans and other species. Introgression has proven to have adaptive values and is quantifiable. It can have several outcomes; it can reduce fitness and create sterility‚ but at the same time it can help
