Paul said: These threads are such a waste of time. If someone can't be bothered to go through the vast amounts of research that has been done or is too dull to comprehend what it means, a few paragraphs in a video game forum definitely won't convince them. "and as far me not supporting a theory without concrete evidence even though the scientific community says otherwise? That's a completely different story, and one best kept to myself." It's absolutely pointless arguing with the above. It's like arguing with a 4 year old with his fingers in his ears.

You're missing my point...I was saying I support microevolution, but am not fully convinced about macroevolution. I've been told that I'm misunderstanding it, so I'm asking for it to be clarified.
But whatever you say...

I posted a semi-joke post earlier showing how different selections pressures has resulted a wide variety of different domestic dog breeds. That's essentially macro-evolution in practice and shows clear phenotypic differentiation between different breeds descended from a common ancestor.
What some people earlier have said about minor changes in micro-evolution add up and essentially lead to macro-evolution is essentially correct. However, we are still discovering new methods that micro-evolution can advance in the field of epigenetics that can result in a relatively quick change at the macro scale.
Basically, it's not all down to our genes but also how are genes are expressed (which helps explains how we can share nearly 50% of our genes with a banana!). A change in environment results in differences in the expression of our genes. Some being turned off, others stimulating RNA and protein production which essentially alters our body in some way. This expression pattern can then be passed on to our offspring (particularly when the mother is pregnant and changes affect the womb environment). This, on top of mutations and transposons can have major effects and lead to macroevolution as in the dog examples above.
Not that their aren't gaps in our knowledge, but the core of the macro-evolution theory is still correct.
