The preponderance of evidence leaves little room for doubt in my mind about the accuracy of the theory of evolution to explain the observations we consistently make in nature. It's simply the best scientific explanation we have, and it consistently produces accurate results in its predictions, it consistently makes coherent sense of all the data we have.
I have no reason not to accept what is a very well attested and consistently observed natural phenomenon and exceptionally well evidenced theory explaining said phenomenon.

Until the Nuts and Bolts:
Solve this Puzzle...500 years of "evolution" not 500000000000000
Spanish imported horses to America starting in 1493. Spanish were and are renowned for useful and useable horses, Andulasians, Lusitanos, Lippanzer. Also, there is a small herd of primitive horses, Sorraia, which were thought to be extinct (when?) due to meat hunters. The Sorraia are related to Mongollian ponies. Remnant of the Iberian herd was rediscovered in 1920 approx.
The US Forestry conducted DNA test on American feral horses (Mustangs) and concluded the Spanish Mustangs were Sorraia.
The Spanish Government conducted DNA test on Iberian horses. The main lines were Exmore Ponies with a few Sorraia, however so few Sorraia lines exist, the results were inconclusive.
1) Did the Spanish, Cortez, import primitive rare Sorraia or the well bred useful stock? (Did the Spanish equip their expeditions 4 wheel drive vehicles or roller skates?)Historically, good horses were reported to be imported.
2) Did the better bred domestic stock De-Evolve under natural conditions and natural selection into the Original Sorraia without leaving evidence of the more recent breeds in the DNA (My Selection)
3) Could Sorraia have been the original American horse, thought to be extinct, and was in America before the Spanish arrived?
4) Have the Sorraia Mustang evolved or even bred into a different breed than the Sorraia in Spain? If #3 is correct then there should be some evidence of mixing with the later Spanish introduced stock. (? haven't seen any research)
So, can we trace "evolution" of this horse? Do we know anything more about the origin of this "species?"
#2 is serious as it implies that traces of DNA evidence are wiped clean and are not a good record.
