This new behavior could therefore have been the result of cultural diffusion from modern to Neandertal groups. "

Hornwort pyrenoids, carbon[dioxide]-concentrating structures, evolved and were lost at least five times during the last 100 million years "The nonsynchronous appearance of pyrenoid-containing clades, the successful diversification of pyrenoid-lacking clades during periods with low [CO2], and the maintenance of pyrenoids during episodes of high [CO2] all argue against the previously proposed relationship between pyrenoid origin and low [CO2].
