You would think evolution would be a smooth sinusoidal transition with no distinct changes generation to generation. Take the species homo sapiens - man if you will, you'd think there would be a slow changes as primates evolved over time. But it seems to be a step function with distinct sub species and accompanying characteristics "suddenly" appearing. What does that mean - "suddenly" appearing? How does that happen? How can group mutations happen? Let's say a baby is born to paleo human parents with smaller brow and the little baby girl some how more attractive. She would breed small browed offspring but the feature would be eventually washed out. The only way small browed to become dominant and permanently take hold would be a massive small browed mutation simultaneously happening to all tribes all at once. How can that happen?
But brows did get smaller and head shape changed but it "suddenly" appears, with no explanation from the evolutionary paleontologist.
