From Jessica Hamzelou at New Scientist on a study in Iceland that shows that old fathers pass on more mutations than old mothers:
“If a sequence is not present in the parents but is present in the child, then it’s new,” says Stefánsson. They discovered that 80 per cent of new mutations come from the father, and that the number of mutations increases in line with the age of the parents.
…
These mutations won’t all be harmful. We’re all born with at least 70 new mutations, and most of these don’t affect the way our bodies and brains work. “The vast majority of mutations don’t matter, says Leo Schalkyk at the University of Essex. “There might be the occasional mutation that is deleterious, or the extremely occasional mutation that is beneficial.” More.
But Darwinism is natural selection acting on random mutations, creating the thousands of apparently irreducibly complex structures we see in life forms. Enforced in the academy and legislated for the schools. And probability is one of those subjects that, if you dare address it, marks you out as a doubtful person for even wondering.
Darwinism increasingly resembles a totalitarian political philosophy in that the official communications are rigidly controlled but then someone inadvertently gives the game away: But better watch your back if you ever think of trying to do the math.
