Primates are the new kids on the block. The Earth is about 4.5 billion years old and first life occurred about 3.5 billion years ago. The first primate-like creatures evolved about 65 million years ago after most of the world's living species, including...

Any examination of the evolution of birds must start with the Archaeopteryx. In 1861, two years after Darwin published Origin of Species, Archaeopteryx lithographica was discovered in Solnhofen, Bavaria. Preserved in carbonate mud dated as from the mid-Jurassic, the fossil was discovered as two slabs...

Lemurs, the graceful, long, slender limbed animal with long furry tails aremammals, members of the primate order. They are prosimians, a suborder of the primates. The family of lemurs has many species. Fossils suggest that lemurs and their prosimian cousins split from the ancestors of...

Charles Darwin has been credited with the theory of evolution, but in fact he was not the first to consider the idea. Darwin's grandfather, Erasmus Darwin, also began to develop a theory of organic evolution, but it was never brought together in a systematic way...

Fossils are formed when a plant or animal dies and its soft body parts degrade, leaving behind harder parts as leaves, bones, and shells. These hard parts are then compacted repeatedly and increasingly with many layers of sediment, becoming harder over time. While some fossils...
Do Organisms always Evolve into more Complex Forms
By: Xauri'El Zwaan
The theory of Evolution contains no innate expectation that organisms will *always* evolve from simpler into more complex forms. Evolution is an essentially random process of biochemical trial and error. Reproduction of DNA creates random variations of very similar organisms. Those organisms which are best...

It has been speculated by some that humans are ready to evolve, need to evolve and if we as a species do not evolve it will be our doom. Not that it would really matter in the great scheme of things. It would be a...

The theory of evolution, as put forward by Mr Darwin in 1859, refers to the development of more primitive species into more advanced ones through natural selection over time.Our genus, 'Homo' is more advanced than the genus which preceded it, called Australopithecus. Our own...

The first feathered, birdlike fossils have all been classified as Archeopteryx and were discovered in Bavaria in the mid-nineteenth century. There is no fossil evidence of this creature having been descended from dinosaurs, nor do other birdlike creatures appear in the fossil record for another...

In 1946, Joshua Lederberg and Edward Tatum published an article in the Journal of Bacteriology entitled "Gene Recombination in the Bacterium Escherichia coli". This article not only described a new method of genetic transfer among bacteria, conjugation, it would also revolutionize the whole field of...
