According to
wikipedia and a general consensus among archaeologists,geneticists and scientists alike homo erectus, homo ergaster and homo
heidelbergensis, took a specific path out of Africa roughly 2 million years ago. The species homo ergaster eventually became extinct, whereas the homo
erectus and homo heidelbergensis species endured. It's up for grabs to say which species evolved into Cro-Magnon man and which species died out. I
propose that
both species are our true ancestors and
neither died out. I will explain
why I believe this later on. I have
stumbled upon a very recent and hushed debate going on in the archaeological and genetic world via a friend who's an archaeologist here in Sweden.
Here's a couple of charts which, until recently, has been widely accepted as the migration paths of early man.

Notice that over time, Cro-Magnons eventually crossed over into North America (from Siberia) by way of a land bridge called the Beringia land bridge.
Ok, there is no doubt about this. Eventually, they settled all of North America and South America. DNA evidence shows that these settlers of North
America are an exact mtDNA match of the Native Americans of today. So, one can safely assume that the Native Americans of today are direct descendants
of either homo erectus or homo heidelbergensis or
both as I assume. Here's a chart of the natives of the North American continent:
Now, one could assume that homo erectus and/or homo heidelbergensis migrated from Africa and eventually settled into North America. Let me now
introduce what my problem with all of this is. Here in Sweden, the native Swedes are
NOT caucasoid as one would imagine. Our true natives are a
people who refer to themselves as the Saami. Here is a picture:
Look at the similarities between the Saami and the American Indians! Same facial features, even the same abode (in the past, of course!). So, one
could safely assume that the Saami and the Native Americans are from the same DNA? No, they are not! The Saami peoples have the same mtDNA as the
Inuits (Native Alaskans and/or Canadians) but they do not have the same mtDNA as the Kalaallit (Native Greenlanders) nor the (lower) American Indians
of today!. Why is that?
I do not believe that early man exclusively crossed into North American via the Beringia land bridge. I believe they also crossed into North America
via the Northern Polar Cap. Another thing I cannot comprehend is the difference in the mtDNA? One would think the Saami would also be genetically
related to the Kalaallit! However, they are not. This is why I believe
BOTH the homo erectus and the homo heidelbergensis are the ancestors of
us homosapien sapiens!
Please educate me if I am wrong. Thanks for your valuable time.
