 If Darwin had been aware of genes and their typical mode of transmission to subsequent generations, with which statement would he most likely have been in agreement?

#Section 2: Evolution

  1. If natural selection can change gene frequency in a population over generations, given enough time and genetic diversity, then natural selection can cause sufficient genetic change to produce new species from old ones.

  2. If an organism's somatic cell genes change during its lifetime, making it more fit, then it will be able to pass these genes on to its offspring.

  3. If an organism acquires new genes by engulfing, or being infected by, another organism, then a new genetic species will result.

  4. A single mutation in a single gene in a single gamete, if inherited by future generations, will produce a new species.
