I don't get this article. Was there ever any reason to doubt that
natural selection is acting on us?

Is the point that we have actual evidence of natural selection on
current humans, rather than evidence of selection on past humans and
no reason to doubt that it acts on current humans? If that's the
case, I don't get this:

Since when are social factors outside the scope of natural selection?
Animals with bigger brains and sensitive sensors are able to act
socially, which increases their chances of reproducing.

Is the point just that giving birth earlier is being selected despite
other pressures to give birth later?
