One study demonstrated that cross-modal visual and auditory integration is present from within 1 year of life. [101] This study measured response time for orientating towards a source. Infants who were 8–10 months old showed significantly decreased response times when the source was presented through both visual and auditory information ...
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 ...
[1] [2] The paper proposed a mechanism for specific selection for general learning ability. As the historian of science Robert Richards explains: [ 3 ] If animals entered a new environment—or their old environment rapidly changed—those that could flexibly respond by learning new behaviours or by ontogenetically adapting would be naturally ...
[21] [22] If the result of such a failure is favoured by natural selection, genetic assimilation occurs. In the 1960s, Waddington and his colleague the animal geneticist J. M. Rendel argued for the importance of genetic assimilation in natural adaptation, as a means of providing new and potentially beneficial variation to populations under ...

Acclimatization occurs in a short period of time (hours to weeks), and within the organism's lifetime (compared to adaptation, which is evolution, taking place over many generations). This may be a discrete occurrence (for example, when mountaineers acclimate to high altitude over hours or days) or may instead represent part of a periodic cycle ...
