I have a "friend" who believes theres a chance that gene flow can cause cancer. He thinks that perhaps when different races mix, their offspring will have a higher rate of cancer simply because he believes that possibly the mixing of so many different genes can occasionally cause cell malfunctions, namely cancer. He posits that races with less mixing: EG. certain 3rd world tribes etc. will have less cancer rates than cultures that have been interracially breeding. He also believes in a nation like Japan, say it will be shown that before they stoppped their isolationism, will have a statistically significant lower rate of cancer.
How can i prove him wrong? what kind of data can i show him that will stop the argument?
I mean like accessing national database record for Japan and all countries. where would i find this info? How can i PROVE that he is wrong. Where would one go to find statistical national information like this??
He believes that in species where the animals look the same, they will also have lower rates of cancer, not just humans, animals too. How i can get info on this?
Id like to just write a post saying hes wrong, belittling him, and writing ad hominem attacks, but then i would not be worth being a part of this board and i dont want to do that.
Thank you for reading, have a good day![]()
