Have you ever wondered what it's like to make a major fossil discovery? Arizona State University graduate student Chalachew Seyoum and professor Kaye Reed tell us their exciting story.
Seyoum was working as part of a team co-directed by Reed. While searching for hominid fossils at a site called Ledi-Geraru in the Afar region of Ethiopia, he found a fossil jaw sticking out of the 2.8 million year old sediment. That jaw turned out to be the earliest known fossil from our genus Homo. It was around 400,000 years older than any Homo fossil found before. The discovery was published in the journal Science in March of 2015. Dr. Susan Anton from New York University tells us why this find and the time period it's from are important in helping us connect the dots in our picture of early human evolution.
