Do man and ape have a commen ancestor or do they share the same Creator? Science cannot answer this question easily.
What is so unique in man, what is it that makes us different from the animals? A lot more can be said about it - from Biblical and scientific perspective. But is does depend on what you want to look for ...
Studying the differences
We cannot cross fossils and we cannot be sure of their age. We can of course compare and will see that:
The Genesis model
A Genesis model suggests a migration after the Flood resulting in isolation of small populations (resulting in some gene varieties getting lost), leading to different races. Adaptations to the climate were possible because of the variety in the gene-pool: think of bigger noses and smaller skulls in the tropics and the differences in skin colour (a darker skin being a disadvantage in area's with less sunlight). Over time languages lost variety in wording and grammar, as can be shown from the comparison between dead and living languages.
What does our DNA tell us?
Mitochondrial DNA is only inherited through the female line. Studies seem to point towards a recent Eve (see link nr 1). On top of that do calculations show that nine out of ten animal species appeared at the same moment as Man (link 11 - gaat ook over het Y-chromosoom van de mens).
To what extent does the DNA of Chimpanzee match the human DNA? Widespread are percentages of 98% or more, but these are based on hybridising DNA of both organisms - an old and inaccurate technique. In 2002 Britten used a more modern technique to compare DNA-sequences and arrived at 95%. The reason for this larger difference lies in indels: unique genes found only in Man or Chimpanzee. After sequencing the complete genome of Man in 2004 it became possible to really compare the genomes in detail. The first quantitative study (in 2005) showed a difference of 8,5%, with dozens of unique for protein coding genes (not to be found in the Chimpanzee). A new study in 2007 showed that the human genome contains around 1400 unique genes in total.
You should also realise that DNA doesn't tell us the whole story: the use of DNA is what counts as well.
A lot of skeletal material used in the debate about human descent is found in the Olduvai gap in Kenya. High age differences between for instance Lucy (an Australopithecus) and modern Man have been suggested, but new findings seem to contradict these differences.
Ald of these skulls (sometimes only fragments) are found in tuff stonreformed out of volcanic ashes). Chemical analysis of the different strata shows the chemial fingerprint of all these strata to be the same, which makes it very likely these strata were formed in a short time as a result of a single (series of) eruption(s) of the same volcano. Chemical fingerprints are unique and different for each eruption.
