Расширенный фенотип: длинная рука гена

The concept challenges traditional views of genes and traits. I'm curious what inspired the choice to expand this idea into a broader biological context.

The idea that genes can influence environments and behaviors beyond the individual makes me think differently about evolution. How did this perspective change others' understanding of natural selection?

From animal behaviors to human cultural artifacts, I wonder what examples Dawkins might consider as clear illustrations of extended phenotypes.
