You seem to think that nothing happens in evolution until a point mutation occurs. Evolution depends on random variation. That is, in each generation a trait varies from individual to individual. Some have more, some have less but most are about average. In fact, the distribution of variation of a trait in the population will approach a random (that is, a "bell-curve") distribution. That is why the theory is called "evolution by random variation and selection." What it means is that if the environment is stable, most of the population will survive, but the outliers won't fare so well. On the other hand, if the environment changes, there will be already in the population outliers to take advantage of it. Mutations contribute to the production of random variation, but are not the sole or direct cause of it.
I'm not arguing heritable traits.
I'm arguing that random mutation...where a beneficial mutation is extremely rare...has the ability to occur again and again, many, many times in a species progeny....increasing the information in the DNA code substantially....is impossible.
