Collins says he's also excited about other teams producing paleoproteomic studies on cave art: The research can help us understand how early hominins created paints by adding binding agents to ochre and other material, which hints at their cognitive process.

In addition, Dr. Grabowski and the co-authors found that the level of size difference between males and females (sexual dimorphism) appears to have only slightly decreased from earlier hominin species by the time of early H. erectus, and only decreased to modern human - like low levels later in our lineage.

Over the last few decades, however, as subsequent discoveries pushed back the date for the earliest stone tools to 2.6 million years ago (Ma) and the earliest fossils attributable to early Homo to only 2.4 - 2.3 Ma, there has been increasing openness to the possibility of tool manufacture before 2.6 Ma and by hominins other than Homo.
