Homo erectus was the first to walk upright
There are several theories about why our hominin ancestors made the switch from quadrupedal locomotion to bipedal. Some include,
A reduction in body temperature in the hot African sun (by decreasing surface area), energy efficiency which has been laboratory tested between chimps and humans, freeing of the hands for carrying or toolmaking, ecogeographical changes (drier ecosystems resulting in fewer trees), etc.
Yes, they were able to but didn't walk the exact way humans do today
They technically can but they don't do it all the time
Well our ancestors have been walking upright before modern humans came about. As far back as four million years ago the genus Australopithecus was probably the first to walk fully upright.
Yes ., but they also use kunkles of hand for support .

both. she had ape-like features such as her shouders that would allow her to climb, and she had human-like feature such as her pelvis that would allow her to walk upright.

there's nothing special about this. gorillas sometimes walk upright. it's only a web hype.
a human. first they crawl (hand and knees = 4) then they walk upright (2 feet) then they use a cane (2 feet + cane)

The ancestors of dinosaurs walked upright before they evolved into true dinosaurs. The earliest known dinosaur, Eoraptor, walked with upright legs underneath its body.
