Man's Place Among the Diving Mammals.
Fahlman A & Schagatay E 2014 Hum.Evol.29:47-66
....
We compared diving performances in (semi)aquatic & terrestrial spp:
- maximal & average dive depth & duration,
- proportion of time spent under water during repeated dives:
1) Aquatic "deep divers" form a separate group, to which humans & most (semi)aquatic mammals do not compare in diving specialization.
2) Several spp perform dives of intermediate duration & to intermediate depths: a group of "moderate divers".
3) A great nr of spp show more modest diving skills, despite being dependent on an aquatic life or food sources: a group of "shallow divers".

Humans fit well in this latter group:
their maximum diving capacity is well within the typical ability performed by shallow near-shore foragers.
Most accessible food is present near the shores:
have a great nr of air-breathing spp specialized to utilize this niche?
have only a smaller group developed the specialized extreme physiology necessary for extended deep diving?

While foraging in shallow water, humans may repeatedly dive to 20 m, and spend 60 % of the time submerged in shallow diving,
trained individuals have reached depths of 100 m on single maximal dives:
human diving capacity is well within that of typical diving mammals.

How many typical diving mammals can climb 10m vertical cliffs, then run a mile, then ride a bike?
Humans are generalists.

So humans match the characteristics of the typical cliff-climbing mammals?

Hmm. You really need to get out more. Get some air. Honest. It will do you
a world of good.

You simply do not know how to deconstruct a problem -- what questions to
ask, what is relevant.

My little, little boy, nobody denies that:
don't you even know that we evolved from aquarboreal to shallow-diving to wading to walkin??
That's why we can climb cliffs, run a bit & ride (bikes are made for us).
Grow up, DD.

Homo makes tools. Seals don't, dolphins don't, manatees don't, sea otters don't.
Only beavers living along shallow crystalline streams like Homo makes wooden homes and dams.

See? See that? There's your total lack of consistency AGAIN.

Me: "Chimps don't use tools."

Mouth breathers: "Ya they do they hit things with rocks!

Mouth breathers: "Dats tools except when it isn't!"

What's that? A sea otter with a rock. And you like to wet yourself & claim
that banging things with/against a rock is tools cus anywhere you say
"Bang" you can say "hammer" and even though you're using hammer as
a verb you don't know what that means, you're not very bright, so a verb
is a noun and that means they built a hammer & stuff...

You're also "Arguing" intelligent design. Like, there's no way that evolution
could steer dolphins or manatees or SEA OTTERS into any other form than
human, UNLESS MAGIC!

You misspelled "Meant." You want me to ignore the idiocy you
wrote and concentrate on what you "Meant" but were unable
to articulate.

If your fingers spent less time in your mouth than on your keyboard,
and you found a topic for which you have an actual interest, I might
consider that.
