You're getting all mixed up - Yes, it is very likely that Modern Humans came out of Africa - that is the general consensus. But what has that got to do with the common ancestor for Humans and Bananas?
I also never said they came from Pangea, I just used that as an example of how far back we have to go and even said, it was most likely Pangea itself didn't exist. I also said "about" 1.5 Billion because you cannot be exact down to the day of the week. The figure currently being bandied about is 1.576 billion years ago +/- 88 million years.
It isn't a matter of "belief" for me, I am an intelligent person and other intelligent people have done a lot of work and present a lot of evidence to support what they say. That evidence makes sense and fits well with other evidence and other theories.
I apologise if I didn't make myself clear, I realise a low IQ can hamper your reading comprehension.
"God did it" has zero evidence and even contradicts itself, much less corroborate anything else.
I do know a lot about snail genetics. It's my narrow, limited, unintellectual kind of field. In many ways, though, it's a microcosm of evolutionary biology at its worst. Its literature is filled with the great vaguenesses of evolution — with words that, when you deconstruct them, are like shoveling fog; they don't mean much. "Coadaptation," "adaptive landscape," "punctuated equilibrium" — what I sometimes think of as theological population genetics. They're words that don't help at all when you're trying to decide what experiment to do next.
Words like these reflect the view that somehow one gene is there because it has adapted to the other genes that were there already. That the world somehow is a beautifully harmonious structure is an optimist's point of view: everything fits beautifully together, and if you see the whole edifice you don't have to worry about how it's constructed, it just stands up.
That's a pernicious idea. It's an anti-intellectual, working-out-God's-plan, know-nothing kind of idea.
Science is data-led, not theory-led
Although I write a lot about it, I've never done any serious work of my own in human genetics, so I'm a spectator of the subject rather than a participant

Move over bananas! Make room for Uncle Mushroom!
Why are mushrooms more like humans than they are like plants?
But how do we know that that commmon ancestor budded out plants and fungi so far apart that the fungi are closer to us than to plants? We take a look at genetic similarity, and how that kicks over into physiology. There was a marked lack of chlorophyll in the near history of both animals and fungi. We both took a step away from photosynthesis before we started becoming what we are. Fungal cell walls are made of chitin, the same thing that makes up insect's outer carapaces, but is found nowhere in the plant world. Fungal proteins look more like animal than plant proteins. And then there are sterols - important alcohol groups that play a part in everything from biological messenger systems to cell walls

Evidently, it is pointless debating with you for the simple reason you do not understand what a "Theory" is. If you cannot get that most basic of premises through your skull, nothing else is going to get in and it is just a waste of my time trying to get you to learn a word. I spend enough time with my 3 year old doing that and it has to be said, he has a better time of it.
Enjoy wallowing in ignorance

I didn't ask for debate, I asked a question, it was in the title. If you can't answer, then all it comes down to is your opinion. Now it is lunch time, take your child and get it a Happy Meal and be happy the rest of the day. Thank you for your time. I understand and am cool with you not having the answer. BTW, just saying evolution did it is not an answer. You need actual data in your "debate'.

Hmm, since there are skeletons of humans pre-banana in Africa, because bananas were brought to Africa in 327 BC, then I just don't see how humans and bananas can be much related, unless humans came out of Asia instead of Africa. And since very old skeletons were found in Africa, then I wonder how this could fit the timeline.
Perhaps you can answer this one for me. Is it Out of Africa or Out of Asia?

Before we go down this road of "Evolution is only a Theory", let's just make it quite clear it is a Scientific Theory":
Scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. If enough evidence accumulates to support a hypothesis, it moves to the next step—known as a theory—in the scientific method and becomes accepted as a valid explanation of a phenomenon.
When used in non-scientific context, the word “theory” implies that something is unproven or speculative. As used in science, however, a theory is an explanation or model based on observation, experimentation, and reasoning, especially one that has been tested and confirmed as a general principle helping to explain and predict natural phenomena.
Any scientific theory must be based on a careful and rational examination of the facts. In the scientific method, there is a clear distinction between facts, which can be observed and/or measured, and theories, which are scientists’ explanations and interpretations of the facts. Scientists can have various interpretations of the outcomes of experiments and observations, but the facts, which are the cornerstone of the scientific method, do not change.

It wasn't aimed at you, sorry if it looked that way, but I had been trying to avoid using the word "theory" precisely because they latch on to it and do what we know they do, so when you brought it up I thought I'd better leap in there and make sure there is no equivocation about what it means.. Seems that was in vain though as it was promptly ignored.

Is this you Raymond, with a new twist on the banana fallacy? If so... I love you Ray, you give me some good laughs.

How is that "proof" of such a thing?
If anyone has displayed an inability to research and understand, it is you. You can't even wrap your head around what a theory is in Science....
EDIT: Also, I don't believe anyone here was saying they were "liberal and open minded" - that may be the case, but it isn't a pre-requisite for grasping basic science.edit on 27/3/14 by stumason because: (no reason given)
Proving once again that you simply don't invest enough research into anything.
So you take pleasure in beating up this Ray fellow?
Wow, and I thought you guys were open minded and liberal and against all that bullying. But I see you aren't.
Don't worry about who I am.

Bingo. This is exactly my line of thinking.
