My hypothesis is that genes play a much more important role than race. In the image we see large amounts of people both black and white who have an iq lower than 100. However we must be sceptical. What year is this picture from? What source?
This is a bell curve showing results of studies comparing races and ethnic groups with IQ among U.S. test subjects show differences in average test scores (Reynolds et al. 1987)
However there may be bias due to people (value education, in some Asian families a bad grade is shame to the family), educational possibilities (in the US education is not free), drugs usage etc. When we look at the number of people with an iq higher or equal to 130 this is pretty low in all races.
But, within the Asian countries there are vast differences. The average iq of South Korea is 106, Indonesia is 89 and Philippines 86. (IQ and the Wealth of Nations, 2002). That is to say, either education or genes play an enormous role. This means the Philippines (Asian) has about the same bell curve as the black curve, while the South Korean bell curve is much more similar to the asian curve. This is why we could claim that genes play a much more important role than race.
The claim of picture four "These are not the same species" may be false, because a species is defined as the largest group of organisms (animals) where two individuals are capable of reproducing (sexual reproduction).
The other images are jokes and historical events, so no comment on those.
