Most all biologists say “YES,” life did evolved in an unguided way that mimics real design. Specifically, most say life evolved in a Darwinistic way (driven mostly by natural selection).
It might be debated whether most biologists can be considered experts here, however. To be considered an expert on topic x where experts converge on theory y, it seems one should at least belong to a field where, if an alternative to theory y were true, then the experts would know about it. They would be allowed to investigate any such alternative. In biology, however, biologists are not allowed (professionally) to evaluate certain y theories. That is to say, if God created life, and if the evidence favored this theory, biologists operate under methodological naturalism whereby the theory and its evidences are banned from consideration.
• Scott Todd (Dept. of Biology, Kansas State University): “Most important, it should be made clear in the classroom that science… has not disproved God's existence because it cannot be allowed to consider it (presumably). Even if all the data point to an intelligent designer, such an hypothesis is excluded from science because it is not naturalistic. Of course the scientist, as an individual, is free to embrace a reality that transcends naturalism.” [“A view from Kansas on that evolution debate,” Nature, Vol. 410 (30 September 1999): 423.]
