First of all, apologies about the lateness of this post. The school Google connection failed, blocking access to blogger.
Today I introduced the new topic, DNA Revolution.
We can all trace our ancestry back in time. Ultimately we share a lot of our physical traits with our ancestors. For example, if you are of Maori descent then it is likely that you carry some genes from Kupe and other Maori who first colonised New Zealand.
But that is not all. If we go back far enough all humans on the planet share ancestry with the first humans who arose in Africa.
We had an extensive discussion about physical traits.
