No. Why? Because drastic changes can happen in one or a few generations, with only a few key chromosomes of DNA changing at all.
Of course that requires that large portions of populations all change these key chromosomes at the same time, if you want any chance of it sticking. But that's not so unlikely- often there is a common need or ability to evolve amongst a population that is either urgent or explosively beneficial. The onset or end of an ice age, a new source of food, a new environment due to migration or anything else really. All of these could trigger a drastic change in a population
In fact it is only these kinds of scenarios which can trigger speciation, because otherwise the small mutations in DNA which occur amongst individual families would be washed out by the majority in a short time. Therefore it seems highly unlikely that we would find a perfect spectrum of mutations from one species to another, especialy when often times the transitional phase would render a weaker animal less likely to survive.
No, speciation occurs in time with major geographical and social events, at a rapid rate. This is possible due to the conic nature of DNA, and horizontal gene transfer. Evolution is sound
