Entire ethnic groups have arisen in the last 7,000 years. Norwegians, Greeks, Latvians and Bengalis show "major differences" and they all came from the same Indo-European ancestry. How do we know that the Africans did not change? All we have from Africans 70,000 years ago (you got your dates wrong) are skeletons. We don't really know what they looked like beyond that. Skin color is one of the most ephemeral traits. There have been some arguments posted against that statement on SciForums but I find them inconsistent with the evidence and unpersuasive. Bengalis and Lithuanians are separated by no more than 4,000 years of migration. The entire aboriginal population of the Western Hemisphere with its great diversity (except for the Pacific regions of Canada and the USA and the arctic) is descended from one wave of migration generally dated around 13,000BCE but unlikely to be further back than 25,000BCE.
Well i would like to mention the sperm cell, which is the means by which evoultion occurs in humans, the means by which change happens, adaption in humans. sprem cells are created every day in the testicals of males but reach maturity every 72 days. many changes could happen if sperm cell do not reach maturity, if breeding habits change so also will the distiinction of different groups.

Since native Australians are from India, I wonder the second wave went from India to Europe! The single original white Tiger wandered in to the New Delhi zoo sometime ago. So may be that is where (foot of the Himalayas) the single blonde person started...
Where did you read that? All I've ever been able to find on the subject is the no-brainer that they came via what is now Malaysia, at a time when sea levels were much lower and the navigation wasn't as daunting as it would be today, when New Guinea was connected to Australia. In any case this happened at least 40,000 years ago, when most of the ethnic groups we're familiar with didn't even exist yet. There were certainly no "Indians" as we know them, because the Indo-European diaspora out of the Anatolia/Caucasus region only occurred around 3000BCE. I don't think anyone knows who was living in what is now "India" 35,000 years before that. Europe was first colonized by Homo sapiens around 25,000 years ago at the end of the Wurm Glaciation period; before that it was all Neanderthal territory. Since then there have been other waves of migration through the Caucasus, out of Siberia, and by sea. The early migrants brought Europe into the Neolithic Era by trading their nomadic life for permanent villages based on agriculture--farming and animal husbandry. It's not clear whether these technologies were invented independently, copied from neighboring tribe to neighboring tribe in a slow wave westward from Asia, or brought by an immigrating tribe who already had it in their previous homeland. Tracing the bloodlines and immigration routes of these early people has been impossible, although if we find more of their remains, DNA testing might give us a clearer view. We only know them by their artifacts, such as Stonehenge. The only pre-Indo-European people still in existence there is the Basques, and no one has been able to link them to any other contemporary human community. The Indo-European migration around 2500BCE established what is now the dominant population of the continent and built its civilizations. The Indo-Europeans, as noted, originated somewhere in the Anatolia/Caucasus region. The Western Indo-European tribes arrived in separate migrations, starting with the Celts, then the Hellenic, Germanic and Latin peoples (and I may not have that sequence quite right, not to mention some anthropologists say the Romans might be a spinoff of the Celts). The eastern branch populated the Persia/India region and around 500BCE began extending northward, becoming the Baltic and Slavic peoples and building nations on the eastern edge of Europe. The classic "Nordic" features that we identify with Europe come from the Western branch of the Indo-Europeans, not the Eastern branch that begat the modern Indic peoples. Obviously there have been later migrations since the Indo-European settlement of Europe. The Finnic peoples (Finns, Estonians and Sami or "Lapps"), the Magyars, the Bulgars (who were not Slavs but adopted their language) and the Ottomans came from Asia and built nations of their own. The Ottomans and possibly the others were Mongolic tribes. The Jews are a Semitic people who built a huge transnational community. Wikipedia says that white tigers were reasonably well-known in the wild as recently as 85 years ago.
From Journey of Man - PBS documentary As recently as 1969, it was unknown. Wiki needs to cite documents prior to 1968 when a tiger in Delhi Zoo gave birth to a white tiger. They never found the original male tiger that was suspected to have come from outside. I saw the very first white tiger there and the zoo people said it was world's first.
If White Tigers existed in 1915, in easy reach of people, they would have been part of Indian Zoo and British Zoo. Of course white tigers existed long before that - but no one was able to capture and breed them. So until 1968, for all practical purposes they did not exist.
