None of these are true.

- Natural selection has been observed in nature (e.g., antibiotic and pesticide resistance, changes in Darwin’s finches, industrial melanism) as well as in labs.
- It can produce noticeable change quickly (bacteria, insects, and some vertebrate populations have changed within years or decades).
- It does not inherently cause a net loss of genetic information; selection changes allele frequencies and can preserve or increase adaptive information (and new variation can arise by mutation, gene duplication, recombination).
