Yes, my boy, a dryher environment... :-DDD

"These data push back the oldest evidence of C4
grass–dominated habitats in Africa—and globally—by
more than 10 million years, calling for revised
paleoecological interpretations of mammalian evolution."
By more than 10 million years.
"Grasses using the C4 photosynthetic pathway are
ubiquitous across Earth’s low to mid-latitudes,
dominating modern tropical lowland grassland and
savannah ecosystems."
"Every site yielded some paleosol samples with
d13C values indicating that standing biomass
was a mixture of C3 plants and water-stressed
C3 and/or C4 biomass (Fig. 2A)(16, 17)."
Water stressed. Do you understand?

As everybody knows, the hominoid LCA c 20 Ma split in S-Asia into lesser (hylobatids, c 20 spp) & great apes

Nothing to do with the climate work in this paper...
