What to know about 120,000-year-old European fallow deer—tracing the loss of genetic diversity

Researchers from the University of Potsdam, MONREPOS, and Leiden University analyzed 120,000-year-old fallow deer fossils from Germany. The study, published in iScience, indicates that modern fallow deer have significantly lower genetic diversity than their Ice Age ancestors due to climate changes and human migration.

What happened

120,000-year-old European fallow deer—tracing the loss of genetic diversity Gaby Clark Scientific Editor Alexander Pol Deputy Editor European fallow deer have faced a dramatic loss of genetic diversity since the last interglacial period.

Why it matters

This was revealed by 120,000-year-old fossils from central Germany's Neumark-Nord site in Saxony-Anhalt, analyzed by researchers from the University of Potsdam, the MONREPOS Research Center and Museum in Neuwied, and Leiden University.

Common ground

Their results have been published in the journal iScience.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
