I am not attempting to provide answers to all the concerns you raised in just one response. I will make a few comments and see where it goes.

The theory on the Origin of Man states that humans and apes share a common ancestry.

Given the conduct of most humans, it is not with an initial sense of joy that I state, "all humans share a common African ancestry." Even if the theory was as simple as 'humans came from Apes', I would be very cool with that. Apes are not responsible for Slavery and racial discrimination. I am more comfortable being aligned with apes and all other forms of animals than these arrogant and highly destructive so-called humans. Anyhow the facts are we are all related even to the most disgusting humans and other creatures.

Generally speaking the Chinese are not elated to find out they came from the same black people they think are inferior to them. They have long resisted that. Having evolved away from Africa, and not forced out by slavery, they have no automatic entitlement to anything there.

You asked: "And please, a question I would appreciate an answer to is this; how long have the Maori and other peoples like them lived in the Pacific ocean regions?"

"The Maori have a legend – that they came to New Zealand aboard seven ocean going canoes, called Waka. It was the last great human migration – the final leg in an epic journey that started 6000 years ago. But where did the journey begin?

So there are many theories about where the Maori and the Polynesians people came from. One suggests Taiwan. A second, Islands south east Asia and yet a third, Melanasia. Altogether a very difficult and confusing picture. But now, a team of DNA detectives think they've finally cracked it. Their astonishing discovery – is that the men and the women came from different places.

It goes like this... Around 6,000 years ago, a small group of people migrated from mainland Asia and settled in Taiwan. They became a great seafaring culture, and from there they travelled down past Papua New Guinea, they met and took on board local Melanesian guides. The guides were male. And clearly, they must have married and had children. This mix of seafarers reached Fiji, and then eventually moved on again, finally settling in New Zealand just 700 years ago."
