We have plenty of genetic diseases that are passed down and still a thing today. Many of the things you mention vary from extremely painful to deadly in a person. For instance, many Asians cannot tolerate dairy. They’ve actually found out that “white” people “evolved” to be able to handle animal bi-products. Dairy won’t kill most Asians but it will make them anything from gassy to extremely sick.pensmama87:![]()
At least we can surmise that whatever causes people to be ultra sensitive to gluten- or incense- or sulfur dioxide, tobacco smoke and car exhaust- isn’t a hereditary condition. If it was carried in the genes, the trait would have died off centuries ago.I suspect many of these people simply died young, or were those of “delicate constitutions.”
We know these propensities are carried in the genes. For $200 you can send off to companies like 23andme and know exactly what sensitivities your genes dispose you to.
There were most certainly people who couldn’t tolerate a food or smoke. Life expectancy was something like 35 no matter where you lived in the world. It’s 70-85 now in most developed countries.
