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]
A key factor applicable in these coevolutionary systems is the continuous adaptation of strategy in such arms races. Coevolutionary modelling therefore often includes genetic algorithms to reflect mutational effects, while computers simulate the dynamics of the overall coevolutionary game.
Dobzhansky concluded that such seasonal fluctuations were the result of natural selection at work, with temperature acting as the selecting agent. These masterful studies provided concrete support for the theory of natural selection, at the same time illustrating the fruitfulness of combining field and laboratory work in the study of evolution ...
Modern geneticists have inferred the 7 genes studied by Mendel. It is impossible to know for certain, but the identification is possible to a high degree of confidence based on Mendel's description, and the pea varieties grown in central Europe in the 1850s. [5] The table shows that the 7 genes appeared on 5 chromosomes.

It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not.
