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.
Through this process of genetic assimilation, an environmentally induced phenotype had become inherited. Waddington explained this as the formation of a new canal in the epigenetic landscape. It is, however, possible to explain genetic assimilation using only quantitative genetics and a threshold model, with no reference to the concept of ...
In addition, a synapse serves as a junction where both the transmission and processing of information occur, making it a vital means of communication between neurons. [ 10 ] At the synapse, the plasma membrane of the signal-passing neuron (the presynaptic neuron) comes into close apposition with the membrane of the target ( postsynaptic ) cell.
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]
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).
The human brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous ...
Life Story (known as The Race for the Double Helix in the United States) is a 1987 television historical drama which depicts the progress toward, and the competition for, the discovery of the structure of DNA in the early 1950s.
