Re: What do Aussies believe re Evolution?
now what would the great pumpkin think ? (linus is crying)

You're not building a straw man here are you?Natural selection nothing absurd about it, happens all the time, it happening as we speak. Example of this can be seen in species with short life spans , where the creature with the favourable mutation lives and breeds ,the others die and become extinct. Evolution my friends.
Again this may all be an illusion but the evidence is strong that this is what happened on a large long term scale.
To call a theory with a strong body of evidence absurd is absurd. I not saying you shouldn't keep your minds open to other possibilities , I just saying to totally ignore something with such strong evidence is silly. But some people still think the earth is flat despite all the evidence to contrary.
I often wonder why. I suppose it it a source of power, manipulation etc. Why not worship the hand that feeds you? Keep it simple Simon LOL...Man will create something to explain that which he cannot.
And if you let yourself be free to fly? Where are you now? (in a nutshell ???)Yeah, if I had to pigeonhole myself Pat, that's about where I'd be too.
lol - well Pat you can blame Dukey - he's the one who first mentioned it here (to my knowledge). Then again, everyone knows he’s off on some oriental adventure – forget about sniffing the roses – he’s into much stronger stuff than that lol.Wow! I'm one of them, according to the dictionary??? A single word describes my belief..... Anyone else out there like me? LOL

apologiesI think it was 123billion billion billion stars btw. = 123 trillion trillion (elsewhere given as "about 100 x 10^18") - !!
Interesting wording Pat. I guess my involvement in these threads is to bowl a few googlies and hopefully promote some radical thought... to be free to fly, so to speak.And if you let yourself be free to fly? Where are you now? (in a nutshell ???)
spooly what a brilliant youtube ( in fact set of youtubes)Another theory for evolution.
Basically, meteorites containing organic carbon fertilized the Earth

The human cerebral cortex has grown rapidly over the last million years. With it, we've learned to use tools, industrialised, and built nuclear weapons. But the older, primitive parts of our brain are still there—fuelling our emotions, our fears, our greed, our impulse to destroy our neighbours.
What separates us most from other creatures on the planet is the size of our brain. One hundred billion nerve cells, packed into 1400 cubic centimetres - bigger than any other species. Thanks to it, we're the dominant species on the planet—forget the huge jaws and the sharp spines running down the back, who needs them?
It's been a long time in the making though. About a billion years ago, brains were pretty basic—just groups of specialised cells with the ability to transmit electrical signals to move other groups of cells—primitive limbs. The idea was, in an environment where an organism needed to get away in a hurry from another on the lookout for a snack, mobility was a good idea.
gday wysHumans have the greatest ratio of brain to body mass of any animal.
Q1: The is a current theory that all modern humans evolved from a small group in Southern Africa. What is the evidence for this and how convincing is it?
Submitted by Dennis Murray
A:The current model is that modern humans evolved from a small group in sub-saharan Africa. The group had to be reasonably small because there is strong DNA evidence to suggest that the common ancestor in the female line goes back to only 200,000 years ago. You would expect it to be much longer ago if the group was large. There is strong DNA evidence to support this, as DNA of all kinds, not just mitochondrial, is much more diverse in Africa. Basically, modern humans are a subset of Africans.
The group that gave rise to us possibly lived in North East Africa (Ethiopia or Kenya) and just spread out. This group had some sort of advantage over the other groups and species alive at the time - maybe they discovered a new tool type or formed a symbiotic relationship with the ancestor of the dog (dogs keep you warmer, look after kids, have an alarm bark, and possibly help with hunting). This meant they could out-compete the other groups as they spread out.

G`morning 2020........Professor Colin Groves on current models , DNA and dogs.
love it lolmaybe they ..... formed a symbiotic relationship with the ancestor of the dog
Uhm, talking about a strawman.Ultimately, the theory of evolution argues for none other than spontaneous generation. I argue that that is absurd.
