I think this idea of directionality depends on the level of analysis. If you just take just a single snap out of time, again, lucy's not becoming anything. The ision of the species are just doing what they do to survive,. and they're t perfectly well adapted at that particular time. I believe that in regard to sort of biological developments. There may be grander patterns. But mwary about taking scientific evidence into metaphiscal areas.
If extraterrestrial intelligences exist, will look anything like us? Are we alone in the cosmos? If we reran the tape of life, would humans appear again? Is there purpose in the cosmos?
Shermer speaks with Cambridge evolutionary palaeobiologist Simon Conway Morris whose latest book challenges six assumptions that too often pass as unquestioned truths amongst the evolutionary orthodox. These include the idea that evolution is boundless in the kinds of biological systems it can produce. Not true, he says. The process is highly circumscribed and delimited. Nor is it random. This popular notion holds that evolution proceeds blindly, with no endgame. But Conway Morris suggests otherwise, pointing to evidence that the processes of evolution are “seeded with inevitabilities.”
Shermer and Morris also discuss: convergent evolution and directionality in evolution; chance, contingency, and law in evolution; theistic evolution and teleology in nature; why Morris is a Christian but rejects Intelligent Design creationism; free will and determinism; and whether there good arguments for God’s existence.
