Evolution: "just a theory". Scientific caution is sometimes confusing.
What about Lamarkian evolution? I don't think the basic premise holds water, but I do think environment influences evolution. Phenotype drives genotype. The idea that random mutations, for example, drove dolphins and whales from land creatures to sea creatures is hard to understand. However, if living in an aquatic environment droves the changes, nostrils on top of the head and blowholes, it makes more sense. I have no thoughts on the mechanism that drives these mutations, but think somehow environment influences mutation. Any thoughts?
