Mutation introduces new genes. Natural selection changes gene frequency over time.
Have scientists ever observed a mutation that introduced new genes? I thought mutations were genetic copying mistakes that usually hinder progress.
Does natural selection actually help macro-evolution? Natural selection is picking one favorable gene and eliminating a less favorable gene right? To evolve from fish to philosopher there has to be a huge increase in genetic information. These 2 mechanisms seem to limit genetic information not increase it. Are there other mechanisms for macro-evolution or am I missing something?
