Does anyone know how to solve this question? I am so lost. Thankyou!
You are studying the source of new virus that has recentlyinfected humans. You suspect that the virus was transferred fromother primates (they exhibit a similar infection), specificallychimpanzees, gorillas, or orangutans. You sample blood from severalinfected humans and sequence some viral genes. You then build aphylogenetic tree with the human sequences and all the knownstrains from each primate. Draw a hypothetical phylogenetic treethat would suggest that the virus came from gorillas, and thistransfer occurred twice independently. Label chimp sequences (c),gorilla (g), orangutans (o), and humans (h).
