>The primary driver of evolution is symbiosis and not natural selection.
An intriguing claim.

So, there is a body of literature detecting signatures of human evolution over the last 2,000 years in human genomes. Field et al. (2016) and Song et al. (2021) are large birds'-eye papers, for example, and there are plenty of smaller focused ones that detect the evolution of specific human traits over smaller timescales. I remember one in maybe the PNAS which showed that the polygenic score for educational attainment (or intelligence) evolved to be lower among indigenous Europeans over the last century.

The symbiosis of humans with what, exactly, was driving these evolutionary changes over the last 100–2,000 years? Let's take the top categories from the picrel taken from Song et al. (2021)—dermatology (skin and hair color), PGSs for psychiatric disorders, PGSs for cognitive abilities. Awaiting your take on the symbionts here.
