Scientists from Skoltech and Moscow Institute of Physics and Technology (MIPT) studied the protein and lipid composition of a mammoth bone found near the Yana River in northeastern Siberia.
Their study is one of the few pioneering endeavors in paleolipidomics -- a frontier research area that comes to complement paleogenomics and paleoproteomics.
The results of their study were published in the European Journal of Mass Spectrometry.
Advanced methods of genetic analysis have made it possible to study DNA extracted from fossilized bones, giving rise to a whole new trend in science, paleogenetics, that has helped crack a lot of evolutionary mysteries.
Nevertheless, genetics alone is hardly enough to get a full picture of the animals that inhabited the Earth long before humans.
This is why at some point paleogenomics was joined by paleoproteomics that studies ancient proteins.
