Waddington called the effect he had seen "genetic assimilation". His explanation was that it was caused by a process he called "canalization".He compared embryonic development to a ball rolling down a slope in what he called an epigenetic landscape, where each point on the landscape is a possible state of the organism (involving many variables).
The Baldwin effect compared to Lamarck's theory of evolution, Darwinian evolution, and Waddington's genetic assimilation. All the theories offer explanations of how organisms respond to a changed environment with adaptive inherited change. In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution.
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
A study showed that a low dose (0.1 mg/kg) of psilocybin given to mice increased neurogenesis in the hippocampus 2 weeks after administration, while a high dose (1 mg/kg) significantly decreased neurogenesis. [32] No orally-available drugs are known to elicit neurogenesis outside of the already neurogenic niches.
Assimilation is how humans perceive and adapt to new information. It is the process of fitting new information into pre-existing cognitive schemas. [18] Assimilation in which new experiences are reinterpreted to fit into, or assimilate with, old ideas and analyzing new facts accordingly. [19]

Most proteins, which are macromolecules, tend to be flat in taste, but some proteins, such as monellin and thaumatin, are known to be intensely sweet [1]. These sweet-tasting proteins may be used as ...
Assimilation is the process of absorption of vitamins, minerals, and other chemicals from food as part of the nutrition of an organism. In humans, this is always done with a chemical breakdown ( enzymes and acids ) and physical breakdown (oral mastication and stomach churning).
