... It is often believed that human locomotion was an adaptation to the open plains, but when we separate our locomotion into its individual elements, this belief appears to be a just-so interpretation:
a) two-leggedness is seen in birds (including ostriches, flamingoes and penguins), many dinosaurs, and diverse mammals (including hopping mice and kangaroos on the savannah, indris and gibbons in the branches, and lowland gorillas and
proboscis monkeys while wading, though not in most wading mammals);
b) full plantigrady (with the heels usually touching the ground or branch) is, for instance, seen in water opossums and sealions, whereas cursorial animals run on their toes or hooves (digiti- or unguligrady);
c) very long legs relative to trunk length are typical of frogs, kangaroos, indris, tarsiers, giraffes, ostriches and flamingoes, to name a few;
d) straight legs (as opposed to bent-knees-bent-hips in rest) are seen from wading-birds to giraffes, especially in large and heavily-built species;
e) a striding gait (with alternating limbs, as opposed to hopping) is seen in many walking, running and wading birds, and more frequently in larger-sized than in smaller birds;
f) truncal erectness is seen in some arboreal species (especially tarsiers and gibbons), meerkats on the look-out, penguins on land, etc.;
g) a latero-laterally broad trunk is typically seen in beavers and platypuses, and to a lesser degree in brachiating primates (apes and atelids);
h) an alined body (with head, trunk and legs in one line) is typical of swimming animals;
and so on.

Fallacy.

Arboreal slow-striding bipedalism & arboreal slow-swinging bimanualism were the complementary modes of locomotion in ancestral rainforest arboreal hominoids.

Analyse, my little boy, analyse.

Do you call this 'analysis'?

You should take the name "Fluellen"
(from Henry V). Your 'reasoning' is of
the same quality:

FLUELLEN
There is a river in Macedon, and there is
also, moreover, a river at Monmouth. It is
called Wye at Monmouth, but it is out of
my prains what is the name of the other
river. But 'tis all one; 'tis alike as my
fingers is to my fingers, and there is
salmons in both. If you mark Alexander‘s
life well, Harry of Monmouth's life is come
after it indifferent well, for there is figures
in all things. Alexander, God knows and
you know, in his rages and his furies and
his wraths and his cholers and his moods
and his displeasures and his indignations,
and also being a little intoxicates in his
prains, did, in his ales and his angers,
look you, kill his best friend, Cleitus.

GOWER
Our king is not like him in that. He never
killed any of his friends.

FLUELLEN
It is not well done, mark you now, to take
the tales out of my mouth ere it is made
and finished. I speak but in the figures
and comparisons of it. As Alexander
killed his friend Cleitus. being in his ales
and his cups, so also Harry Monmouth,
being in his right wits and his good
judgments, turned away the fat knight
with the great—belly doublet; he was full
of jests, and gipes and knaveries, and
mocks—I have forgot his name.
