Slave and "servant" genes. I've been reading about the shocking conditions experience by forced or "tricked" early settlers into Australia and the USA. They were more or less all slaves or experienced similar conditions. Aside from the initial journey, which would have killed anyone weak, or with a weak immune system there was seasoning, followed by a brutal 7 years of constant work, beatings and diseases. There must have been an element of natural selection which may not be evident in the current day populations but may well have been evident back then. I will mention that even if you were not a slave or servant, mortality rates on these journeys were still high. I can't see how, with >50% (and lets face it likely as records back then weren't the best) of your population selected in this way (if you were not strong you just died) that there was no lasting impact on the gene pool. I'd like to highlight, without having to write it down that the condition's experienced by servants and slaves were as horrendous as anything experienced by humans on this earth ever. What do the forum scientists have to say ?
