Human Evolution: Making Sense of Ancient DNA
In May 2008, a pinky bone was found in a cave in Siberia (Wikipedia: Denisova Cave) and soon news reports enthusiastically claimed to have found a new human. Soon scientists had to revise their hypothesis and thinking due to new modern state-of-the-art molecular analysis, which lead to updates in the evidence for events in human history twice: in 2010 and 2015.
Briefly sum up the significance of the discovery in the Denison Cave and explain the difference between the initial and recent classification of the discovery.
You do not need a summary of the discovery, as you’ve already dealt with the topic in your last exam and prepared to present the topic in class.
Your tasks are:
Explain the difference between the initial and recent classification of the discovery and outline how the method of PCR (Polymerase Chain reaction) can be useful in the investigation.
