An effect of the environment on intelligence is evident in rapidly increasing intelligence quotient (iq) test scores around the world. this phenomenon is called the Flynn effect.
<h3>
What is the Flynn effect?</h3>
The IQ test results have risen over the past century, according to the Flynn effect, which was first identified in the 1980s by researcher James Flynn. Widespread agreement on this impact has been observed by researchers who are investigating it. One study that integrated the findings of other published studies (which involved a total of more than 14,000 individuals) and was published by psychologist Lisa Trahan and her colleagues discovered that IQ scores have definitely increased since the 1950s. Despite some known outliers, IQ levels have generally risen over time, according to academics. The Flynn effect's existence is rarely contested, according to Trahan and her co-workers.

The increase in species with the area in which they occur (islands, lakes, etc.) is one of the first empirical patterns identified by ecologists and biogeographers.
In classical metapopulation models extinction and immigration determine the persistence of a species in a patch system. Here we will do basically the same thing, only this time we will consider several species at the same time and instead of population size our interest will be the number of species in each spot, which in this case will be islands.
