In the early days of western exploration of the world, many native tales of unknown animals were initially dismissed as mythology or ... far unproven tales and traditions regarding unknown undescribed animals in native folklore should not be summarily dismissed in the same way. There are ...

These antibodies mistakenly recognized native T lymphocytes as foreign antigens , and consequently the T ...

Structural biology

... circular dichroism . Most often researchers use them to study the static " native states " of macromolecules. But variations on these methods are also used to watch nascent or denatured molecules assume or reassume their native states (see e.g. protein folding ). A third approach that structural ...

Carolus Linnaeus

Each race had certain characteristics that members supposedly had. native Americans were reddish, stubborn, and angered easily. Africans were black, relaxed and negligent. Asians were sallow, avaricious, and easily ...

Charles Darwin

... Darwin's work during the Beagle expedition let him study at first hand geology, fossils and a multitude of living organisms as well as meeting native peoples. He methodically collected an enormous number of specimens, many new to science, which established his reputation as a naturalist and made ...
