Each month, we publish a roundup of new human origins research supported by Leakey Foundation grants. This is the science your support makes possible.

This month's open-access research highlights include a study of sibling stress, an investigation of pant-hoot communication, and a comparison between fossils from two European Paleolithic research sites.

Every month, Leakey Foundation grantees publish research that helps us understand humanity's past, present, and future. We've gathered three open access articles about discoveries funded by our donors.
