Trace Deep Evolutionary Relationships

The relationships between major groups of organisms remain unclear, limiting our understanding of life's history and constraining comparative biology research. This challenge involves resolving the tree of life for all major groups using genomic, morphological, and fossil evidence. Barriers include ancient divergence times, horizontal gene transfer, extinction events, and integrating multiple data types. Without clear evolutionary relationships, comparative studies will be flawed, evolutionary understanding will be incomplete, and biological research will lack proper phylogenetic context. Success could complete the tree of life, improve comparative biology research, reveal major evolutionary transitions, and provide the framework for understanding all biological diversity while advancing multiple fields of biology.
