Read and understand · 1/3Why can the El Mirón genetic traces help researchers study this period?

Read the answer and explanation

Human skeletal remains from the period are scarce. The first paragraph notes that human skeletal remains from the period are scarce.

Clue: Sediment from El Mirón Cave in northern Spain has yielded human nuclear DNA from a layer dated to approximately 22,000 years ago. Researchers used the genetic traces to investigate a period when human skeletal remains are scarce.

Read and understand · 2/3What does the evidence from the cave support?

Read the answer and explanation

Ancestry related to earlier western Europeans persisted through a cold phase. The second paragraph describes the persistence of ancestry related to earlier western European populations.

Clue: The results support the persistence of ancestry related to earlier western European populations through a particularly cold phase of the last Ice Age. Because the material came from sediment rather than a single identified skeleton, the evidence offers a different window into who occupied the cave.

Read and understand · 3/3How does the article distinguish the study from the later university account?

Read the answer and explanation

The study appeared on October 23; the university discussed its contribution on October 30.. The final paragraph gives October 23 for the study and October 30 for the university account.

Clue: The study appeared in Science Advances on October 23. The University of Cantabria discussed its regional contribution on October 30; ScienceAlert revisited the work on November 1.

Your turn

Explain what the El Mirón sediment suggests about ancestry and how this evidence differs from analysing one identified skeleton.

See one possible answer

It supports the persistence of ancestry related to earlier western European populations through a cold phase of the Ice Age. The DNA came from sediment, so it provides a different view of cave occupants than DNA from one identified skeleton.
