Sigh. Too difficult apparently. Or just trying to be funny?
I'll try again, in simple words:
If a rule applies for all animals, what makes you think it does not apply
for humans? (Creationists think humans are unique...)
Simplistic example:
All furless + fat mammals spend a lot of time in water (no, not the reverse,
my children...), so what makes you believe humans must be an exception?
I'm not saying they wer no exception, I'm only asking why you claim they
were an exeption.
Understood?


Lee, science is about what can be *repeated*.
Since you think we are the one & only Homo, you can't say anything sensible
on the subject.
(Which I knew, of course: so far you haven't said much sensible on our
past.)

Just analyse human features.
Look in what animals you can find comparable features.
Then compare these sorts of animals.
There are no savanna mammals among them.
There are a lot of semi-aquatics among them.

Not difficult. Even you can do it, Lee...

In 1993, I compared 68 human features to apes (control), to arboreal
mammals, to plains-dwellers, to semi-aquatics & to full aquatics.
My conclusions:
- we once had arboreal ancestors,
- we never had plains-dwelling ancestors,
- we once had semi-aquatic ancestors,
- we never had fully aquatic ancestors.

"Aquatic versus savanna: comparative and paleo-environmental evidence"
Nutrition & Health 9:165-191, 1993.

"This paper begins by comparing anatomical and physiological features of
humans and other groups of mammals (apes and arboreal mammals, open-country
dwellers, fully aquatic mammals, and semi-aquatics), in order to establish
the nature of the environment where Homo originated. It concludes that the
evidence completely invalidates the savanna theory and strongly favours the
semi-aquatic hypothesis. The second part points out that nothing in the
fossil record disproves this conclusion, and quotes paleo-environmental
evidence concerning the milieu where the ancient hominids fossilised."

Concl.: "Although the paleo-environmental data alone are not enough to
invalidate the savanna theory conclusively, in combination with the
comparative evidence of fossil and extant hominids, they completely
invalidate this unlucky and far-fetched theory, and strongly suggest that
the arboreal lifestyle of our primate ancestors was followed by a
semi-aquatic mode of life in a tropical or subtropical milieu, probably at
first a mixed arboreal/aquatic lifestyle. Since more than two million years
and until less than hundred thousand years ago, fossil Homo species seem to
have frequently dived and waded in lakes, seas and rivers, where they
partially fed on shellfish."
