Evolution of Caffeine and its Methylated Sequences
Explore the evolution of caffeine through natural selection, evolutionary relationships, and convergent evolution in plants such as Camellia (Tea), Theobroma cacao (Chocolate), and Coffea (Coffee). Discover the unique methylation sequences specific to Theobroma cacao and the similarities/differences in methylation patterns in Camellia (tea) and Coffea (coffee).
