Why does sharing so many genes between life forms prove evolution? Does that show a bias by scientists? Could it more likely prove a Creator? Is it possible they are misreading data? Isn’t it possible to look at all the historical information available and come up with numerous false scenarios? Is it possible that all the historical data reveals a Creation?
The purpose of this study was to reconstruct a minimum genome for the last common ancestor for all animals.
It does not “prove” evolution, since nothing is ever proven in science. It does, however, provide strong evidence in support of the evolutionary model.
A salient feature of evolutionary theory is the concept of change over time. That is what the study in this article has shown, in great detail. Furthermore, the nature of the change is exactly what we would expect to see in a system where evolution is the fundamental driver of diversity of the biome.
A creation event implies static genomes. It also implies that any organism should be equally different from any other organism in its class. There are any number of inferences one could make on the assumption that life exists because of a singular creation event in which all existing organisms came into being. But observation tells us that none of those inferences is actually accurate.
Is there an ultimate creator who created a universe in which life could arise, evolve, and exist? That is not a question that is easily answered by scientific inquiry. Personally, I think that the existence of physical laws that allow for life to exist is worthy of a great deal of wonder and awe.
