Overview
Analysis of six ancient teeth, estimated to be around 400,000 years old, has yielded proteins that are thought to correspond to *Homo erectus*. This molecular evidence provides insights into the relationships between *Homo erectus* and other hominin groups, specifically suggesting a link with Denisovans.
Research Context
The study sought to extract and analyze ancient proteins from archaic human remains. The focus was on remains from a period and species where molecular data has historically been less accessible. Understanding the molecular connections between *Homo erectus* and other hominins is a significant area of paleoanthropological research. Obtaining such ancient protein data can offer novel insights into evolutionary lineages and interconnections that might be difficult to discern solely from morphological analysis.
Approach
Researchers utilized six teeth, dating back approximately 400,000 years, as the source material for their investigation. The methodology involved extracting and identifying ancient proteins from these dental remains. The identified proteins were then analyzed to determine their potential origin and to assess their implications for hominin relationships. The study aimed to leverage the stability of ancient proteins, particularly those found in dental structures, to reconstruct evolutionary links.
Findings
- Six teeth, approximately 400,000 years old, yielded ancient proteins.
- These proteins are hypothesized to belong to *Homo erectus*.
- The molecular clues derived from these proteins suggest relationships between *Homo erectus* and other hominins.
- Specifically, the findings indicate a connection between Denisovans and *Homo erectus*.
