The jawbone above was discovered in Ethiopia some months ago.
The jawbone is the earliest known specimen on the Homo- lineage and suggests that the earliest man lived about 2.8 million years ago. Human evolution is believed to have taken place between 2-3 million years ago, when man began resembling modern humans.
The Pangea super continent is said to have started breaking apart around 200M years ago, according to the Continental Drift theory posited by Alfred Wegener in 1912 and evidenced/proven around 1962.
From this information then, it’s easy to conclude that:
1. The so called evolution took place long after the continents had drifted much apart. 2. There was no chance that monkeys or before-man-beasts had swam to different continents and evolved on them.
Then a question arises, how is it that Africa is the cradle of humankind? Wazungu walifikaje Europe, Asians alifikaje Asia?
How comes human races show some kind of differentiation(colour, eyes, facial structure)?
Thus, man must have began evolving before the continents drifted apart.
Do you believe in evolution theory? Creation theory? Or spontaneous chance? Carbon dating to me seems to suggest ridiculous aeons in which stuff formed and happened.
dude, the explanation is there, africa, asia europe are all linked, google sinai peninsula.
then when ocean levels drop, there exists a land bridge linkimg far east to alaska. from there indians migrated south till south america. then Polynesians just moved by boat
The bridges and boats must have come much much later. When Christopher Columbus discovered America, he found red Indians. How did the red Indians get to America from negro land? I also wonder how we came to have different colors, red, brown, yellow.
some of what you are pointing out are not really big differences (not differentiation as you call it). small mutations could have accumulated over time due to exposure to different environments hence bringing these differences in skin colour and tone. Alternatively, some genes may or may not be expressed due to these environmental conditions hence bringing about these physical differences that we see. This is a big field of study today called epigenetics. This presence or absence of expression is passed on to the offspring and that is how we are today, just like the way females dont grow beards like men even though we have the same genome.
What amazes me is how Polynesians were able to occupy those small islands in the pacific
That is very simplistic. Mutations are rare events and mutations that would bring such a huge difference even more rare because there is always a dedicated repair mechanism. No, they will never turn yellow.
I also think mutations are more rare in huge animals than in small animals. Am I wrong when I suggest drug resistance of pests and microbes is due to mutation?
mutations occur when cells are breaking up to form sperm/ovum, therefore the more often you reproduce the higher the chances mutations will occur. in a good environment, bacteria reproduce every 30 min. when was the last time you reproduced
The fact is the continents fit into each other like jigsaw. And it is true that they move apart or towards each other by six inches or so every year. The other thing is dry land is connected to each other from cape town to the tip of south america with exceptions of a few straights and Islands, which might actually be recent formations. The closest relatives to native americans are the chinese, mongols and the likes and some of the amazonian tribes look strikingly mongolian. Exreme east of russia is next to north america. They are actually neighbours.
