NOVA Season 2 Episode 2 In Search of Human Origins

In season 2 episode 2 of NOVA titled "In Search of Human Origins," viewers are taken on a journey through time and across continents as scientists work to uncover the mysteries of our early human ancestors. The episode kicks off with a visit to Ethiopia's Afar region, where a team of researchers is excavating the remains of a hominid that lived more than 3 million years ago. These early human ancestors, known as Australopithecus afarensis, were first discovered in the 1970s by a team led by paleoanthropologist Donald Johanson.

As the team digs deeper, they uncover new clues that help them piece together what life was like for these ancient hominids. For example, they find a number of small stones that were likely used as tools to break open nuts and other tough foods. They also discover evidence that suggests these early humans may have lived in family groups, which would have helped them to better defend themselves against predators and other dangers.

From Ethiopia, the episode travels to South Africa, where scientists are working to understand the evolution of the human brain. The key to their research lies in a group of early hominids known as the australopithecines. These creatures lived more than 2 million years ago and are the earliest known hominids to show signs of a larger brain size. By studying their brains and comparing them to those of other primates, including chimpanzees and gorillas, the scientists hope to gain new insights into the evolution of our own species.

The episode also explores the work of Lee Berger, a paleoanthropologist who has spent years searching for fossils in South Africa's Cradle of Humankind. In 2013, Berger and his team made headlines when they discovered a new species of hominid, which they named Homo naledi. The discovery was particularly exciting because it suggested that early humans may have engaged in ritualistic behavior, as the fossils were found in a hidden chamber that would have required intentional burial.

Throughout the episode, viewers are introduced to a wide range of scientists, each with their own set of research questions and methods. Some use high-tech imaging technology to create 3D models of fossils, while others painstakingly sift through dirt and debris to uncover tiny fragments of bone. Despite these varied approaches, all of the scientists share a common goal: to uncover the secrets of our early human ancestors and learn more about our own evolutionary history.

Overall, "In Search of Human Origins" is a fascinating look at the world of paleoanthropology and the ongoing quest to understand where we came from. The episode is packed with scientific insights and fascinating discoveries, making it a must-watch for anyone interested in the history of our species. Whether you're an expert in the field or simply a curious viewer, there's something in this episode to captivate and inspire.
