Austrapithecus (australopithecines)
An early ancestor of humans is called Australopithecus. This species is known for its upright posture and bipedal locomotion, and is considered an important transitional form in human evolution.
Homo erectus is an extinct species of archaic humans that lived between approximately 2 million and 140,000 years ago. They are considered to be the first human ancestor to have modern human-like body proportions and abilities to control fire. Homo erectus is believed to have originated in Africa and spread to other parts of the world.
Homo erectus is also known as "upright man" because of their upright posture compared to earlier hominid species. They were an extinct species of archaic humans that lived between 2 million and 117,000 years ago.
Australopithecus is considered the first species believed to have walked upright. Fossils of Australopithecus show evidence of bipedalism, indicating they were able to walk on two legs, which was a significant step in human evolution.
According to scientists, an Australopithecus Afarensis is a Latin term to describe early human species in Eastern Africa between 3.85 and 2.95 million years ago. This species had an apelike appearance which included a flat nose, projected lower jaw and etc., however, they were still able to walk upright like humans. The species were known to live in trees and on the ground.
mammals / humans are considered primates because we are the superior species, stand upright, and give birth to live offspring after mating process.

Homo erectus
Homo erectus is an extinct species of human that lived approximately 1.9 million to 140,000 years ago. The name "Homo erectus" means "upright man" in Latin, referring to their characteristic upright posture.
The Flamingo.
Seahorses evolved their upright posture some 35 million years ago. The pygmie pipefish is a common ancestor to the seahorse.
The first species believed to have walked upright on two legs is Australopithecus afarensis, with the most famous example being the fossil "Lucy" discovered in Ethiopia. This early hominin species lived approximately 3.9-2.9 million years ago.
