Genetic tradeoff: Harmful genes are widespread in yeast but hold hidden benefits
The genes responsible for inherited diseases are clearly bad for us, so why hasn't evolution, over time, weeded them out and eliminated them from the human genome altogether? Part of the reason seems to be that genes that ...
