CURRENTLY the region is considered subtropical but if you want to go with the "No Evidence" card we can start with apply "Homo" to the name, or the fake "Intentional burials" and any imagined tools... it's age... brain size... the "Modern"
brains...
Virtually everything has been bullshit. You know, there were indisputable apes
found in a cave very, Very, VERY close to Rising Star but even before that I openly wondered if they had just found an extinct species of Pan and were attributing a whole lot of bullshit to it, seeing how everything they had told us
was bogus.
I mean, what was accurate? The age? Not even close. The oh so "Modern" skeleton? Nope. The "Modern" brain? Not that. The "Intentional Burials?" Utter
nonsense. They appear to have even invented an anomalous find just to exaggerate some range in brain size along with it's importance.
Why? I mean, who gives a shit?
It's all consistent. All the bullshit is consistent. If it were accidental it couldn't
be. It would be more random. But it's all consistent with a very modern, very human "Ancestor" even though it clearly is not.
Why?
Is there a prize for it? Does the Nobel committee issue an award for Greatest Work in Fiction?
It's all consistent and it's all bullshit.

ordinary features in modern humans. Are
they purely random or cosmetic? Or are

As is traditional -- in THIS discipline -- you
have no concept of niche, or awareness
that humans/hominins occupied one.
Your attitude to possible changes in the

more different. Do you think that (say)
foxes 5 ma looked or behaved differently?

Most land animals swim while breathing, like human dog paddle, no coiled hair except on tropical human heads.Nearly all small to medium land animals
have fur. When they (or their descendants)
adapt to water, that fur becomes thicker.

didn't they lighten their heads, like mini-brain hobbits? Instead they got bigger heavier
heads & brains.
The reason that they insulated their heads
(with dense coils of hair) and increased the
size of their heads and brains is that the
water was cold, and survival was
determined more by the ability to cope
with the cold than by any gain they might
make in speed of swimming.
Raft-wrecked survivors probably swam as
a group, hopefully in the right direction.
They would have reached the shore more
or less together. Those with the biggest
heads were less likely to fade (and die)
on the journey. Any 'extra fast' swimmers
that went ahead, were more likely to go
in the wrong direction.

In the modern world shipwrecks

Nope, mostly on reefs & rocks near land, as always.Dubious. But being wrecked in a storm
on a rocky shore won't have a good
survival rate. Not many modern ship-
wrecked sailors survive by swimming
to the shore.
earlier (paleo-) times, on much flimsier
craft and with no life-jackets, they
would usually have avoided risks, not
have gone far out, and their chances
of survival would have been much
higher.
Those that could
swim that distance (in cold water)
would usually survive and pass on
their genes.
Far less significant than swimming across rivers.River-crossings would have been
dangerous, but not often undertaken.
(They were not migratory, like caribou).
Fishing with nets (sometimes using
rafts) would have been a common
activity.

I've no idea on what you based

No arctic animals have coiled fur. Caribou swim across many rivers, no coiled fur.How many times do I have to point out
that caribou have (and their ancestors
had) a dense coat of fur? That was
never an option for hominins, with their
primate (i.e. chimp-like) inheritance.
They had to lose their chimp-like hair,
since they sometimes had to sleep on
damp ground.
