The clanobacteria are descendants of the ehloroplast. The choloroplast arose from within the cyanobacterial phylum. The chloroplast and the cyanobacteria are not related, compared with today, the temperature on Earth during its first half-billion yean was probabl considerably warmer. considerably colder. about the same as today. about the same as today on average, but the diurnal fluctuations were much greater.
