Summary

Story summary

Researchers sequenced microbial DNA from woolly and steppe mammoths, uncovering DNA over one million years old.
They identified 310 microbial species, including bacteria linked to African elephant deaths.
Six groups, such as Actinobacillus and Pasteurella, may have caused diseases in mammoths.
The study suggests microbes influenced mammoth adaptation and extinction.
Findings pave the way for future research on ancient microbiomes and health impacts.
