The discovery of 1.77-million-year-old Homo erectus skulls in China has been reported, suggesting that early humans may have reached Asia earlier than previously believed. The finding appears to challenge existing timelines of human dispersal, with the skulls representing the oldest evidence of the ancient human relatives in East Asia. The age of the skulls has been confirmed, with estimates indicating they are nearly 1.8 million years old, although the interpretation of the discovery has been met with some differing views.
