this whole thread is really sad...there is so much evidence pointing towards evolution that it's mind-boggling

the most obvious (so that everyone

can understand): look at selective breeding-from the wolf, humans bred wolves with specific variations (genetic mutations/natural variance among organisms) to get the desired animal...and now we have everything from yorkshire terriers to great danes and mastiffs, and sheep dogs, and pitbulls, etc.....and this was also used for other tamed animals....but this is evolution done by humans, and sped up

another point: Genetic code
DNA-many advances have been made recently in the unravelling of human's DNA, many from the Human Genome Project. Some of their findings include that we are 98% alike to yeast in our genetic code. This shows how life went from primitive roots to complex beings through a series of mutations over billions of years. In every human cell, there are 3 billion base pairs of DNA coiled to fit in the nucleus. Every time that cell divides, it must copy each base pair until there are 6 billion base pairs. Now think of how many times cells have divided since life began. How many chances for mistakes. The mistakes that were harmful resulted in the death of the organism and its genetic code. If the change was beneficial, then the organism and its offspring would be more likely to survive, and in turn, pass on their genetic material. Now, after billions of years, we have organisms as advanced as we are.

Third point: mitochondria and prokaryotes (mainly bacteria)
Some organelles in our cells have DNA independent of the nucleus DNA. These organelles are mitochondria (in plants, chloroplasts). Mitochondria divide indendently of the cell and replicate their DNA. Mitochondria are similar in structure to prokaryotes, and display identical DNA replication. This form of replication is more simplistic than eukaryotic DNA replication (we're eukaryotes) and is used by prokaryotes in the exact same way. This shows that our cells evolved from primitive prokaryotic cells into more complex structures.
