Humans are all lactose tolerant at birth; they then have a mechanism that shuts this tolerance off after weaning. Most humans today have lost that mechanism, so they become lactose persistent. However, this is a loss in genetic information because of the loss of the mechanism, so it is still downhill selection. You can’t keep pointing to examples of downhill selection (something creationists support) to try and prove that uphill selection happens all the time (something creationists do not support).
Incorrect. It is a genetic mutation, not a loss of genetic information.
