Tracing the Origins of COVID-19
This chapter investigates a recent study proposing early COVID-19 cases in Shanghai and the implications of lineages A and B in relation to the virus's origins. It emphasizes the need for further scrutiny of both the laboratory and wet market theories, discussing inconsistencies in data and the weak evidence supporting raccoon dogs as a source. Additionally, the chapter highlights findings indicating that the virus may have emerged earlier than originally thought, providing critical insights into its evolutionary timeline.
