40,000-Year-Old Individual from Asia Provides
Insight into Early Population Structure in Eurasia

"In Brief
Yang et al. show that the genome of a 40
kya individual from Tianyuan cave near
Beijing is more similar to Asians than to
Europeans, past or present. His similarity
to a 35 kya European and to individuals
from some South American populations
suggests a persistence of population
structure in Asia that lasted until the
colonization of the Americas."
"SUMMARY
By at least 45,000 years before present, anatomically
modern humans had spread across Eurasia [1–3],
but it is not well known how diverse these early populations
were and whether they contributed substantially
to later people or represent early modern human
expansions into Eurasia that left no surviving descendants
today. Analyses of genome-wide data from
several ancient individuals from Western Eurasia and
Siberia have shown that some of these individuals
have relationships to present-day Europeans [4, 5]
while others did not contribute to present-day
Eurasian populations [3, 6]. As contributions from Upper
Paleolithic populations in Eastern Eurasia to present-day
humans and their relationship to other early
Eurasians is not clear, we generated genome-wide
data from a 40,000-year-old individual from Tianyuan
Cave, China, [1, 7] to study his relationship to ancient
and present-day humans. We find that he is more
related to present-day and ancient Asians than he is
to Europeans, but he shares more alleles with a
35,000-year-old European individual than he shares
with other ancient Europeans, indicating that the separation
between early Europeans and early Asians was
not a single population split. We also find that the Tianyuan
individual shares more alleles with some Native
American groups in South America than with Native
Americans elsewhere, providing further support for
population substructure in Asia [8] and suggesting
that this persisted from 40,000 years ago until the colonization
of the Americas. Our study of the Tianyuan individual
highlights the complex migration and subdivision
of early human populations in Eurasia"
