Hi Afra, I like your game. It's fun. So I will play. The card you are playing now seems to be that we humans got the Thalassemia mutations from the monkeys and apes who lived in Greece 15 million years ago because we evolved from those ancestral Greek primates. Consistency with your original assertion would demand further that the mutations in these distant Greek ancestors would have had to be naturally selected by evolutionary pressure from severe forms of malaria. The card I have contradicts your contention. It says the following, and it is the current scientific understanding: 1. Humans evolved from primate ancestors in Africa, not Greece. The type of monkeys and apes found in Greece 15 million years ago do not figure in our direct evolutionary lineage. 2. The types of malarial parasites against which Thalassemia provides some protection evolved less than a million years ago. In fact, Plasmodium falciparum, the most deadly of such parasites evolved no earlier than 7000 years ago. It first evolved in Africa, then spread to the Middle East and the Mediterranean region, then Southeast Asia, and finally, only about 500 years ago, to the Americas. 3. Evidence indicates that Thalassemia mutations emerged in humans by natural selection due to evolutionary pressure from severe forms of malaria only over the past 3000-5000 years. It coincided with the period of development of agricultural communities in Africa and the Middle East 4. The malarial parasites that infect apes and monkeys do not infect humans. Cheers, Santosh
