> He had isolated the genes which caused aggression

In 1950s, genetics was a mystic art. By 1975, world renowned bee expert Charles D. Michener writes that Warwick had identified 8 genes for aggression:

> Kerr, because of correlations between some of Stort's characteristics, attributed the effects to eight genes.

Nowadays, those of us who work in the field of genomics, seldom speak of particular genes, but sections of chromosomes identified by coding. The idea of "genes" even seems old-timey at this point.

> The word "gene" originally arose as a derivative of pangene, a term used to describe entities involved in pangenesis, Darwin's hypothetical mechanism of heredity. The term derives from the Greek genesis ("birth") or genos ("origin"). The term gene itself was first used by Wilhelm Johannsen in 1909, based on a concept Mendel had developed in 1866.  

> To the modem genomics scientist, the classical image of a gene and the extended dogma associated with it are quaint. High-throughput experiments that simultaneously probe the activity of millions of bases in the genome deliver a far less tidy view.
