They found that the more the population grew, the faster human genes evolved.

他们发现人口增长越多，人类的基因进化得越快。

He had been comparing the virus genes with human genes to see if the virus might have evolved to mimic our own proteins.

过去他一直在比对人和病毒的基因，看病毒是否能演化模拟出人的蛋白质。

Previous research suggests these genes evolved in response to millions of years of retrovirus infection.

先前的研究表明，这些基因是宿主与逆转录病毒感染百万年斗争的进化结果。

Most so-called cancer genes are actually misfunctioning versions of genes that have evolved specifically to stop cancers from forming.

ECONOMIST: Genomics

So, newly evolved variants of the targeted genes take the place of the originals, without altering the rest of the genome of the bacteria.

FORBES: Putting Evolution to Work

This observation has led to the assumption that disease-related genes are recently evolved for the older a gene is, the more likely it is to be part of the irreducible structure of being alive, and therefore the more likely it is that breaking that gene will be fatal.
