Palmitoylethanolamide (PEA) is an endogenous fatty acid amide, and lipid modulator. [2] A main target of PEA is proposed to be the peroxisome proliferator-activated receptor alpha (PPAR-α). [3] [4] PEA also has affinity to cannabinoid-like G-coupled receptors GPR55 and GPR119. [5]

The eight Neolithic founder crops (emmer wheat, einkorn wheat, barley, peas, lentils, bitter vetch, chick peas and flax) had all appeared by about 7,000 BC. [30] Traditional crop breeders have long introduced foreign germplasm into crops by creating novel crosses. A hybrid cereal grain was created in 1875, by crossing wheat and rye. [31]
(Evolutionary ecology, Population genetics, Molecular ecology, Evolutionary biology, Ecological genetics) Selaginella moellendorffii, remnant of an ancient lineage of vascular plants that is key to understanding the evolution of land plants. It has a small genome size (~110Mb) and its sequence was released by the Joint Genome Institute in early ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Evolutionary biology, in particular the understanding of how organisms evolve through natural selection, is an area of science with many practical applications. [1] [2] Creationists often claim that the theory of evolution lacks any practical applications; however, this claim has been refuted by scientists.

In biology, evolution is change in the heritable characteristics of biological organisms over generations due to natural selection, mutation, gene flow, and genetic drift. Also known as descent with modification .
