When the Neo-Darwinian Synthesis emerged in the 1930s and 1940s, mutations were said to provide the natural variations that natural selection worked on to produce all new forms of life.

However, directly contradicting mutation’s central role in life’s diversity, we have seen growing experimental evidence that mutations Neo-Darwinian theory represents mutations as uniquely biological events that constitute the ‘engine’ of biological variation.

In America the towns of Chaco Canyon are built in this period. According to an article, 'Prehistory of Warfare', by Steven A. 1000AD: Otto III visits the Shrine of St Adalbert in Poland and the tomb of Charlemagne in Aachen.

The Theory of Evolution is strong enough that nearly half these examples could be disproved and the evidence would still be fairly overwhelming.

There is so much in this world that only makes sense in the light of Evolutionary Theory. Some of these layers are from the decomposition of sediment, others come from chemical precipitation, others from decaying organic matter, and others from volcanic lava.

And even once the antiquity of the remains was established, many scientists refused to accept that Neandertals could be closely related to modern humans, depicting them instead as brutish and apelike.

This interpretation reflected the prevailing prejudices about human ancestry, and was supported by misinterpretation of the remains of the "Old Man of La Chapelle", whose skeleton was warped by arthritis.

Thirty years ago, it was generally accepted that humans and the great apes last shared a common ancestor perhaps 16-20 million years ago, and that the separate human branch was occupied by only a few species, each evolving from the one before.

Now we know, through a combination of new fossil finds and molecular biology, that humans and chimpanzees diverged as little as 7 million years ago, and that our own lineage is "bushy", with many different species in existence at the same time.

De Vries was so enamoured with mutations that he developed an anti-Darwinian saltationist theory of evolution via mutation alone.

But as more became known, mutations of large effect were found to be universally lethal, so only mutations of small effect could be credibly considered as of value to evolution, and de Vries’ saltationist theory waned.

Olaf Trygvasson dies following his defeat by Sweyn Forkbeard.
