as an example; tiger is the species - then you have sub-species such as the bengal tiger and the siberian tiger. different sub-species of tiger vary in size and colour depending on where they live. so when we talk about race in humans do we actually mean sub-species? because we vary in size and colour depending on where we live. im just wondering if sub-species would be a more appropriate term than race.
thanks
