The evolution of hominoid locomotor versatility: Evidence from Moroto,
a 21 Ma site in Uganda.

Abstract

Living hominoids are distinguished by upright torsos and versatile >locomotion. It is hypothesized that these features evolved for feeding
on fruit from terminal branches in forests. To investigate the
evolutionary context of hominoid adaptive origins, we analyzed
multiple paleoenvironmental proxies in conjunction with hominoid
fossils from the Moroto II site in Uganda. The data indicate
seasonally dry woodlands with the earliest evidence of abundant C4
grasses in Africa based on a confirmed age of 21 million years ago
(Ma). We demonstrate that the leaf-eating hominoid Morotopithecus
consumed water-stressed vegetation, and postcrania from the site
indicate ape-like locomotor adaptations. These findings suggest that
the origin of hominoid locomotor versatility is associated with
foraging on leaves in heterogeneous, open woodlands rather than
forests.

This has to be true because monkeys never eat fruit. If they
try they explode, and then herds of rampaging unicorns
charge through the forest, trampling any monkeys they see
attempting to so much as grab at fruit.

"Ah, science!"

The largest monkeys are the Mandrills. According to your Wiki
they max out at about 66 pounds and 3 feet in length.

Not huge.

Of course these are outliers -- the single biggest, actually appear
to be something of a case of parallel evolution as they are often
mistaken for baboons -- and it's not exactly honest to base
anything on outliers.

It's claiming that the EXCEPTION is the rule...

Supposedly just over 50% of their diet is fruit.

At it's surface this might seem to support the crazy idea that the
ancestor to humans ate fruit, and this was somehow different
even if it wasn't. After all, this monkey eats a lot of fruit and it
already doesn't look like a monkey!

Oh, who am I kidding? It's dumb.

In English it's called "Rationalizing."

It's also called a "Circular Argument."

They lack any means in the Out of Africa purity model to account
for hominoids, and they CONCLUDE an African origins they are
RATIONALIZING, inventing anything they can gasp at as an
explanation to justify the conclusion that they already came to.
