My two cents: I suspect we will get a better grasp on human evolution once subsaharan and middle eastern countries have stronger, better funded indigenous institutions for paleontological and paleoanthropological research.
The tricky relationship between palaeontology and poor countries
WHAT YOU see depends on where you stand. The unarguable fact that most palaeontologists live in the rich world means two things. One is that the fossils of these places are far better studied than those of poorer countries, which is a scientific pity. The other is that what knowledge has been garnered about poor-country palaeontology is frequently the result of visits by rich-country palaeontologists.
All this was well known, if not quantified, before Nussaibah Raja put numbers on it in a paper published in Nature Ecology and Evolution. Ms Raja, however, sees not just a regrettable history-induced bias that should certainly be addressed in future, but also a continuing pillage of poor countries by the scientific establishments of rich places more powerful than they.
