The huge gap at 29:28 showing 120 to 150 mya (wow, just about 30 mya), shows a tremendous gap of assumptions to me. To think that between that much time is needed complex bird like features like in the Archaeopteryx:
"Archaeopteryx skeletons had pneumatized vertebrae and pelvis. This indicates the presence of both a cervical and abdominal air sac, i.e., at least two of the five sacs present in modern birds. This in turn indicates that the unique avian lung design was already present in what most evolutionists claim is the earliest bird." (P. Christiansen and N. Bonde, Axial and Appendicular Pneumaticity in Archaeopteryx, Proceedings of the Royal Society of London, Series B. 267:2501–2505, 2000.)
To simple assume that this is the time needed..., for myself I prefer to believe that God created everything already with an immense diversity and what we have today is less diversity. Its decreasing in diversity and with an increasingly factor of animal extinction.
In other words I think, personally, that God instead of using gradual variation over and nature pressure, he used polymorphism and DNA codification. He programed every kind, every functionality, every characteristic, every molecular machinery is His creation. He also programmed in DNAs, within fauna or flora, the possibility for immense customization, such customizations are realized through a very well designed biochemical process that occur protected inside the animal body, inside a kernel. This is interesting when for example the already programed functionality of crossing-over or gamete duplication reveals variation of characteristics that stays in agreement with the specie in question, not changing to a new kind. Change of kinds? of course you will contradict Genesis 1:21 if you want so much to elaborate a theory over new kinds formation over a common ancestor. To grip on that theory you will simple make a fool of yourself because you never saw how difficult its to design a structure
Also Adam and Eve lived thousands of years ago! What are the implications of that? They had a extremely better DNA codification then we have. Enabling then to live much more.
