No signal of a super-archaic origin of the Denisovan AMBN gene, a comment on the protein affinity of Homo erectus and Denisovan enamel proteins.

Ioannis Patramanis, Frido Welker, Laurits Skov

The paper challenges a model proposing Denisovan AMBN introgression from Homo erectus by showing no signal of super-archaic origin in late Denisovans.

Assessing the potential of ancient protein sequences in the study of hominid evolution

Ioannis Patramanis, Laurits Skov, Enrico Cappellini, Fernando Racimo

This study evaluates how ancient protein sequences can inform hominid evolution, showing they provide limited resolution compared to DNA data but can still offer insights when combined with better modeling.
