This particular species is the longest lived and most recognizable of all human ancestors, they lived between, approximately, 3.85 and 2.94 million years ago In fact, the species may have lived for nearly 900,000 years, which makes them a prominent species for 4 times longer than modern man has existed (Smithsonian National Museum of Natural History).
Australopithecus afarensis was only a 1/3 the size in comparison to modern human’s today. It has characteristics of both human and ape ancestry. They possessed flat noses, thick, protruding lower jaws, a small brain, long curved fingers, and long legs that had adapted to upright walking. By studying their dentition we can learn about the kinds of foods they were adapted to eat and what foods they may have actually been eating. Researchers are confident that Australopithecus afarensis survived on a primarily plant-based diet, consisting mostly of leaves, seeds, roots, and nuts, however they might occasionally consume insects and small vertebrates like lizards. (Smithsonian National Museum of Natural History). Australopithecus afarensis represented a unique bridge between the times when human ancestors began to walk upright. They had the ability to both walk bipedally, but also the ability to efficient climb and maneuver in the trees (Choi 1). In 1974 the first nearly intact skeleton of Australopithecus afarensis was discovered. The female fossils, found in the Hadar region of Ethiopia, were given the name Lucy and she became the quintessential example of human evolution, inspiring a book, “Lucy: The Origins of Mankind” that introduced the ideas of human evolution to the mass public. (Hirst). Other famous finds have included the “Dikika,” or child skeleton and the Laetoli find, which included fossils, but, also, the first bipedal footprints ever found. Like human beings today, our most ancient ancestors were highly adaptable to their environments, so

According to the report the universe comprises various materials that undergo different processes resulting to an alteration in their form after some period. Similar processes have been seen to influence the morphology of various organisms. Some aspects of the altered traits may be passed on to the next generation.
As the human species, the most intelligent form of the animal kingdom belongs to this genus; it has been studied and researched extensively in order to satisfy human curiosity. The widely held view is that the genus originated in East Africa sometime in-between 5-10 million years ago and evolved from the Australopithecines of the primitive world (Web, undated).
Humans have evolved through evolution. Aristotle was the first biologist that identified humans as rational animals that have a distinctive ability to reason and make judgments, due to which they are different from other animals.
Its discourse has always been characteristically comprehensive. The study of such broad subject is, unfortunately, contained in the context of time, resources, facilitator’s field specialization, and most importantly, the audience’s initial perception and final reception.
Variation can be with respect to behaviour and appearance (Solomon, Berg & Martin, 2004). Inheritance - Some traits in organisms are passed on from parent to offspring while other traits are a result of environmental conditions. Heritability of traits influenced by external conditions is very weak.
According to Heinrich, before agricultural evolution, humans spread throughout the globe, Therefore surviving in the different habitats did not only depend on the specific genetic configuration, but depended also on large body of cultural information transmitted across the groups, abilities, and other skills that no human could have comprehended alone.
In his works, Darwin highlighted that various living organisms existed, not because of the creation, but through natural selection that lasted numerous million years. Owing to Darwin’s standpoint of evolution, numerous critics began to
Human beings have undergone many changes and are still evolving and becoming more complex. Darin argued that humans originated from the family of apes and chimpanzees and evolved with time to become who they are today.
