Homo sapiens are relatively pathetic athletes by all measures.
Claiming we evolved to run, instead of walk, is like claiming that
we evolved to sing, instead of talk.
Look around. Seriously. Go to any busy shopping center or city
street. People are walking. Little children walk. Old ladies walk.
Everyone walks.
Probably, we first evolved song:
singing was one of the preadaptations to talk.

Vocalizations. But more similar to yodeling, screaming (etc)
than speech.
Regardless of DNA, we probably needed symbolic thought before
language could arise.
Associations between situations & sounds/songs.

It means that we can't look at the routine
everyday activity of a species and come
to firm conclusions about the selective
forces establishing their morphology --
and certainly not as regards modern
humans, whose daily behaviour is as
relevant to that issue as is that of
animals kept in zoos.
200 years ago the great bulk of the
human population spent most of their
time bent over tending crops and fields.
We have to identify those 'critical
activities' in which success or failure
determined death or survival, or
enabled/disabled breeding success.

Not songs. That's attributing singing to chimps, hyenas,
elephants... you name it.
Elephant trompetting.
Gibbon song.
Those are just labels that we apply. The distinction is in your head.
Lots of animals vocalize. They attract mates. They warn of danger. But,
they don't have speech.

Elaine noted that orangutans can whistle.

Was Man More Aquatic in the Past? p.181-189which is also seen in non-human hominoids, and (b) a descent of the hyoid bone relative to the palate, which is less obvious in non-human hominoids, and which is accentuated by the absence of prognathism in the short and flat human face.

"Seafood, Diving, Song and Speech"
In this paper we present comparative data, suggesting that the various elements of human speech evolved at different times, and originally had different functions.
Recent work by Nishimura [1-6] shows that what is commonly known as the laryngeal descent actually evolved in a mosaic way in minimally two steps: (a) a descent of the thyroid cartilage (Adam’s apple) relative to the hyoid (tongue bone), a descent
Comparisons with other animals suggest that (a) the first descent might be associated with loud and/or varied sound production, and that (b) the second might be part of an adaptation to eating seafoods such as shell fish, which can be sucked into themouth and swallowed without chewing, even under water.
We argue that the origin of human speech is based on different pre-adaptations that were present in human ancestors, such as (a) sound production adaptations related to the descent of the thyroid cartilage associated with the territorial calls of apes,(b) transformation of the oral and dentitional anatomy including the descent of the hyoid, associated with reduced biting and chewing, and (c) diving adaptations, leading to voluntary control of the airway entrances and voluntary breath control.
Whereas chimpanzee ancestors became frugivores in tropical forests after they split from human ancestors about 5 Ma (million years ago), human ancestors became littoral omnivores. This might help explain why chimpanzees did not evolve language skills,why human language is a relatively recent phenomenon, and why it is so strongly dependent upon the availability of voluntary breath control, not seen in other hominoids, but clearly present in diving mammals.

For human males, success in fighting
and war would be a major factor.
There are birds outside my window singing. None of them are aquatic.

Yes, the endur.running nonsense is the most ridiculous hypothesis imaginable.

None of them have snorkel noses.

That's all argument those outdated kudu runners have...
