Australopithecus Climate Struggles

The Australopithecus Afarensis is an extinct hominid who existed over 3 million years ago. During this time, the Earth was undergoing various climate changes. These climate changes took place roughly 7 million years apart from one another, and have been known to cause evolution to occur. The Australopithecus demonstrated various aspects of these evolutions while it existed. Climate changes have lead to the development of bipedalism, which the Australopithecus was able to use. In turn, we know that the hominid was able to use its hands, greatly increasing its survivability and abilities in general. With regards to mobility, the Australopithecus was also able to migrate throughout the continental. If the environment was not suited for the their survivability, they were able to shift to a more favorable area. Also, with the productivity increase with the use of hands, Australopithecus had the option to use tools. However, climate changes also have lead to increases to the cranium, something the Australopithecus did not have. Thus, their use of tools would be quite limited, as well as their communication.When looking at their teeth, they are quite similar to homo sapiens, but they have much few teeth, and look to be quite flat. Meaning, their diet must have been limited to certain foods. The climate plays a drastic effect on food, allowing certain fruits and vegetables to grow in specific locations, as well as providing habitable environments for certain animals. Luckily, the Australopithecus was able to migrate, allowing the species to survive for over a million years. The climate may be what causes species to become extinct, but as the Australopithecus has shown, it also further develops the process of evolution.
