Ancient evolution theory in Hinduism

There is an interesting insight on how evolutionary is being depicted through the ten incarnations of the Hindu Lord Maha Vishnu. This is what it is believed to be.

Matsya(fish) to Kurma(tortoise-amphibian) to Varaha(boar) to Narasimha(half-man/half lion) to Vamana(dwarfed man-with stunted growth) to Parasurama(axe wielding primitive man) to Rama(justly king-epitome of goodness) to Krishna(worldly wise-machiavellian) to Buddha(enlightened one) to ?

The last incarnation is believed to be Kalki Avatar. The incarnation He takes to destroy the world which is equivalent to that of what other religions believe to be "judgement day".

There is another belief of how Lord Surya's (Sun) had seven chariots which correspond to the seven colours of the spectrum.

It is fascinating that our forefathers knew well about science which we know of today. In the Golden and Silver Ages, some civilisations were known to have used technology more advanced than ours. Just imagine, people in those days used technology greater than that of computer's.
