A high degree of genetic similarity (as high as 99% according to some studies) between humans and chimpanzees leads evolutionary biologists to conclude the two species share a common ancestor. However, a closer look at the genomic data presents a less certain and far more complex picture. It shows significant differences between humans' and chimps' gene expression and regulation—most notably in regard to brain structure.
We would expect the Creator to make use of common designs when populating the Earth with life, and yet He introduced something entirely new when He made Adam and Eve. As the only creatures "made in His image," humans are endowed with capacities uniquely associated with spirituality. Evidence shows no indication that these capacities and behaviors emerged gradually. Instead, they seem to have appeared suddenly. RTB's creation model accommodates for the differences and similarities scientists see in the genomic data.
