# Lee Berger's Quest: Unraveling the Mystery of an Extinct Human Species
Written on
Chapter 1: From Law School to Fossils
In an unexpected twist of fate, Lee Rogers Berger found not only his career path but also a drowning woman on the same fateful day. A Georgia native, he had just returned home after leaving Vanderbilt University, where his dismal grades in law contrasted sharply with his stellar performance in electives. This realization directed him towards journalism, where he began his journey as a local news photographer.
While covering a story by the Savannah River, Berger caught sight of something unusual out of the corner of his eye. Without hesitation, he jumped into the water, became a local hero, and unwittingly discovered a unique talent: the ability to be in the right place at the right time.
Years later, he employed a similar instinct in his professional life. While pursuing his Ph.D. in paleoanthropology in 1994, he began fieldwork in South Africa after receiving advice from Donald Johanson, who co-discovered the famous hominin fossil known as Lucy. Despite initial successes in the "Cradle of Humankind," Berger's career slowed to a near standstill.
On his first day at a new site, they stumbled across 21 undiscovered cave locations.
In late 2007, feeling disheartened, Berger became the "last person on Earth" to discover Google Earth. He plugged in GPS coordinates from the sites he had surveyed and realized they were inaccurate, leading to a frustrating realization that three years of work had been wasted. This prompted him to return to the field, albeit to a location just a kilometer away from his previous digs.
On that first day, while walking with his son Matthew, the nine-year-old came across a hominid clavicle. By the end of the week, Berger had uncovered 125 new cave sites and about 14 fossil locations. By July 2008, he had identified over 700 cave sites, culminating in the discovery of Australopithecus sediba, a find that established him as a pivotal figure in paleoanthropology.
Section 1.1: The Facebook Appeal
In late 2013, Berger's luck struck again when cave explorer Rick Hunter shared photographs of fossil-laden chambers within the Rising Star Cave, part of the same site. However, the cave's narrow 7.5-inch entrance posed a significant challenge for Berger. Undeterred, he took to Facebook, seeking "tiny and small specialized cavers and spelunkers" willing to work pro bono. Within a day, he received around 60 applications from eager young explorers, ultimately selecting six, whom he dubbed his "underground astronauts."
As a result of this unconventional recruitment, the extinct species Homo naledi was discovered, with over 1,500 skeletal fragments recovered, marking it as one of the largest finds of its kind.

Section 1.2: Criticism from the Establishment
Despite his remarkable achievements, Berger's methods have drawn criticism from traditional paleoanthropologists. Detractors argue that his rapid approach leads to inaccuracies and suggest that he should enlist seasoned researchers who have dedicated years to mastering specific anthropological niches. Tim White, an anthropology professor at the University of California Berkeley, cautioned that rushing research could be perilous.
Berger is well aware of the scrutiny—it's a byproduct of his field. "Paleoanthropologists can be a bit like silverback gorillas," remarked Patricia Kramer, an anthropology professor at the University of Washington. "The new, brash group is often a target."
In 1995, Berger co-authored a paper on a singular fossil found at the Taung site, proposing that the fossil's isolated condition and skeletal damage could be attributed to a predatory bird's attack. Initially ridiculed, this "Taung bird of prey hypothesis" eventually gained acceptance as a plausible explanation.
Subsection 1.2.1: The Philosophy Behind Discovery
With confidence and humor, Berger describes his approach as a blend of "fortitude or stupidity." Nevertheless, his strategy has undeniably yielded significant results.
Chapter 2: Significance of Homo naledi

In this engaging video, Jeremy DeSilva discusses the discovery of Homo naledi, examining its implications for our understanding of human evolution and the complexities of the species.
Section 2.1: Why This Find Matters
Berger emphasizes that the assemblage of hominid fossils discovered is unparalleled. Homo naledi exhibits a combination of characteristics: a large brain, apelike shoulders, human-like arms, curved fingers, a primitive pelvis, long legs, and human-like feet. These features reveal the existence of numerous lineages yet to be uncovered and challenge the traditional linear narrative of evolution.
"We must reconsider what it means to be human," Berger asserts.
Section 2.2: Changing the Landscape of Paleoanthropology
Contrary to claims from senior anthropologists that fossil discoveries have dwindled, Berger points out that the richest hominin site in Africa was located less than a mile from the continent's most extensively explored region. "This indicates that extraordinary findings are still waiting to be uncovered," he argues.
Berger describes naledi as a "complex species," suggesting that they may have intentionally disposed of their dead—an act once thought to be exclusive to modern humans. This notion raises questions about self-awareness and mortality in early human relatives.
Section 2.3: Addressing Misconceptions
When discussing burial practices, Berger warns against myths, such as the existence of "elephant graveyards." While animals may exhibit grief, they do not consistently practice burial like humans. "Humans universally dispose of their dead, regardless of familial ties," he explains.
Berger encounters various outlandish theories about how bodies ended up in the caves, from alien abductions to sensationalized accounts. He dismisses these as distractions from the real significance of the findings.
Section 2.4: Bridging Generational Gaps
Berger attributes some of the criticism to generational differences, noting that his generation of scientists has grown up with technology and the Internet, enabling rapid communication and collaboration. He believes that involving the broader scientific community can expedite research without sacrificing quality.
Despite the critiques, Berger remains steadfast in his approach, advocating for the value of engaging early-career scientists and using new technology to advance the field. He views the fossils as a legacy for future generations.
Section 2.5: The Impact of Open Access
Berger's team adopted an open-access model, allowing global engagement with their findings. The response has been overwhelming, with millions of individuals learning about Homo naledi soon after its discovery. "We've replaced the Kardashians for 24 hours," he quips, highlighting the widespread interest in paleoanthropology.
Conclusion: A Call for Reflection
Berger hopes that such discoveries prompt humanity to reflect on its connection to the natural world. "If we fail to recognize our place within nature, the consequences could be dire for all living beings," he cautions.
Sidebar: Hominid vs. Hominin
The terms "hominid" and "hominin" can be perplexing, as their meanings have evolved over time. Hominids encompass all modern and extinct Great Apes, while hominins include only specific genera such as Homo and Australopithecus. Homo naledi, thus, falls under multiple classifications, highlighting its unique position in our understanding of human evolution.
