Topic: Intelligent design - IS IT possible? Is closed so I will give you my answer here in a new guest book.

Soderqvist1: Mutation is not new genes added, mutation is changed sequence in the nucleotides.
The Eukaryote cells has been radiation dated as approximately 2.0 billion years old! And all plants, animals, and humans are organisms of eukaryotes, because we share the same genetic-language! For instance, just as protein molecules are chains of amino acids, so DNA molecules are chains of nucleotides. The nucleotide building blocks come in only four different kinds, whose names may be shortened to A. T. C. G. these are the same in all plants, animals, and humans included too. What differs is the order in which they are strung together. The G. Building block from a man is identical in every particular to a G building block from a snail. But the sequence of building blocks in a man is not only different from that in a snail. It is also different – though less so- from the sequence in every other man, except in the special case of identical twins.

It is also possible to see similarities between species whose ancestors diverged into separate species many, many, millions years ago. In fact, all mammals share a common body plan. For example there is a one-to-one correspondence between the bones of a human hand, the bones in the front flipper of a whale, and the bones of the wing of a bat. The same correspondence is seen in all tetrapods, including birds, amphibians, and reptiles. A tetrapod is an organism with four limbs, and five digits, a horse (five digits in a hoof) is also a tetrapod, and so is a bird, which has two legs and two wings. The same bones are seen in the leg of a frog, the wing of a bat and the arm and hand of a human being. Our ancient fathers are Australopithecus, to Homo Habilis, to Homo erectus, to Homo Neanderthal and Homo Sapiens, and lot of fossils can be found here in my links to Universities and museums!

Soderqvist1: there is no sharp difference between microevolution, and macroevolution!

Conclusion
There is no difference between micro- and macroevolution except that genes between species usually diverge, while genes within species usually combine. The same processes that cause within-species evolution are responsible for above-species evolution, except that the processes that cause Speciation include things that cannot happen to lesser groups, such as the evolution of different sexual apparatus (because, by definition, once organisms cannot interbreed, they are different species). The idea that the origin of higher taxa, such as genera (canines versus felines, for example), requires something special is based on the misunderstanding of the way in which new phyla (line ages) arise. The two species that are the origin of canines and felines probably differed very little from their common ancestral species and each other. But once they were reproductively isolated from each other, they evolved more and more differences that they shared but the other line ages didn't. This is true of all line ages back to the first Eukaryotic (nuclear) cell. Even the changes in the Cambrian explosion are of this kind, although some (eg, Gould 1989) think that the genomes (gene structures) of these early animals were not as tightly regulated as modern animals, and therefore had more freedom to change.

The distinction between microevolution and macroevolution is becoming a favorite one for creationists. Actually, it's no big deal. Macroevolution is nothing more than microevolution stretched out over a much greater time span.

Soderqvist1: Answers to your questions about fossilization can be found in this link above, Richard Dawkins has answered the Alabama State Board of Education, in layman terms. With quotes and reply, same as we are doing here!
