Race is much more than skin colour

Not only is race more than skin colour, but race is MUCH more than skin colour. The differences between races are numerous. Perhaps the best proof lies in our DNA. Races have different genes, DNA tests can tell you which race you are from through these genes. These genes produce differences in a whole range of areas. Disparities in physical characteristics such as bone size and structure, chemical make-ups in the body such as hormone levels, behavioural distinctions because of differences in the brain, biological differences such as mating behaviours and gestation periods. These differences all add up and ultimately amount to great differences in societies created by each race. Some differences are quantitative because we know what they are and can measure them to some degree of effectiveness, for example intelligence is different between races and can be measured by IQ tests to a decent degree of accurate representation, or discrepancies in testosterone levels are easily measured. Some differences are necessarily qualitative because we do not fully understand them and/or cannot measure them, but we can deduct their existence based on an understanding of history and evolution and also by observing differences in outcomes that would presumably be affected by different levels in the hypothesized trait. An example of this could be differences in empathy, which are difficult to measure without in-depth sociological/anthropological behavioural studies/experiments that are basically impossible due to our hyper sensitive PC culture. However there have been some basic studies which give us some insight, as well as our own observations and common sense we can see how different races treat each other, treat outsiders, and treat animals. Also, our knowledge of evolution tells us that different climates produce different traits that are beneficial to their respective populations. A harsh climate such as northern Europe and Asia, which has seen some mini ice ages, would seem to require a higher level of teamwork to survive, more so than the rich fertile lands of tropical Africa, where food grows easily and temperatures are conducive to relaxed lifestyles. Traits that would help with greater teamwork would be high emotional intelligence, high levels of empathy, and an inherent mechanism that would prevent social disruption and increase social trust, aka guilt. Just as different breeds of dog are all part of the same species and can breed with each other, yet remain distinct and have recognised differences in behaviour, temperament and intelligence. Humans are the same species and can breed with each other, but can be broken up into sub-species, aka breeds, aka different races. These races (the main ones being, Whites, Asians and Negroes) are a social construct with semi-abstract cut-offs. Race is techincally a continuum with many peoples found in between the main races and even between the secondary races (such as the Arab, which is technically Caucasian). However due to geography these cut-offs make sense, most races were contained to continents because of large oceans or large deserts, and thus the classifications we have constructed to label and identify members of each race are very useful. In later rounds I will talk in more detail about studied differences, and what these differences may mean. I am happy to provide sources for almost all claims, except for the most obvious ones that common sense will be required for, such as that evolution, genes and genetic mutation is real. 5000 characters allowed each round with 3 days to argue each round. Please avoid ad hominem arugments such as "youre a racist" etc. We are only here for the truth.
