The estimate for when this bottleneck occurred has been going back further in time for decades.

Do the Google. There was a major impact event or events roughly
800k years ago. Events of that nature had to produce a severe
climate catastrophe. Had to. This was not optional.
Major impacts can be (and many sources claim "Are") worse than
a super volcanic eruption, because the energy is released all
at once instead of over days/weeks/months.
So we have a bottleneck that is literally carved in stone. It's
there, the evidence exist preserved in the earth's layers. And
yet your source isn't finding the slightest <pun> Impact </pun>
on human evolution, though it swears to find an evolutionary
bottleneck.... just not this one.
It's stupid.
Molecular dating sucks rotten eggs through a straw. It just
does. It exaggerates age, often times wildly so. We would
anticipate and even predict that any genetic consequences to
the impact event would look older than it really was.
The only mystery here is WHY people insist on pretending otherwise.
