Morphology of a male skeleton shrimp, Caprella mutica Morphology in biology is the study of the form and structure of organisms and their specific structural features. [1]This includes aspects of the outward appearance (shape, structure, color, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of internal parts like bones and organs, i.e. internal ...
Structural variation studies became increasingly popular due to the discovery of their possible roles and effects in the human genome. Copy number variation is a very important type of structural variation and has been studied extensively.
Stephen J. Gould and Richard Lewontin proposed biological "spandrels", features created as a byproduct of the adaptation of nearby structures. Gerd B. Müller and Stuart A. Newman argued that the appearance in the fossil record of most of the phyla in the Cambrian explosion was "pre-Mendelian" [a] evolution caused by physical factors.
In the United States, authors such as Marshall Sahlins and James Boon built on structuralism to provide their own analysis of human society. Structural anthropology fell out of favour in the early 1980s for a number of reasons. D'Andrade suggests that this was because it made unverifiable assumptions about the universal structures of the human ...
The capabilities of the human brain and the human dexterity in making and using tools, has enabled humans to understand their own biology through scientific experiment, including dissection, autopsy, prophylactic medicine which has, in turn, enable humans to extend their life-span by understanding and mitigating the effects of diseases ...
NEW YORK (AP) — Researchers have uncovered a simple structure from the Stone Age that may be the oldest evidence yet of early humans building with wood. The construction is basic: a pair of ...
Human genome projects are scientific endeavors that determine or study the structure of the human genome. The Human Genome Project was a landmark genome project. There are numerous related projects that deal with genetic variation (or variation in the encoded proteins), e.g. organized by the following organizations:
The human foot evolved as a platform to support the entire weight of the body, rather than acting as a grasping structure (like hands), as it did in early hominids. Humans therefore have smaller toes than their bipedal ancestors. This includes a non-opposable hallux, which is relocated in line with the other toes. [7]
