If there were a clear prospect that such evils were part of a barbarian past, then at least we might find a small crumb of comfort. No such prospect exists: no scientific analysis can even remotely answer or account for past and present horrors of human behaviour.
It is my opinion that human history can make no sense unless evil doings are recognized for what they are, and that they are bearable only if somehow they may be redeemed.
The fact that some things are mysterious or that they touch on mystery isn't in some way a capitulation, and one should realize that there are some things that we may never understand and, to that extent, should be humbled by that.
The Burgess Shale is not unique, but for those who study evolution and fossils it has become something of an icon. It provides a reference point and a benchmark, a point of common discussion and an issue of universal scientific interest.
I would argue that in any habitable zone that doesn't boil or freeze, intelligent life is going to emerge because intelligence is convergent.
I think the intellectual consistency of Christianity in historical evidence is frankly overwhelming, but my materialist colleagues regard me as a slightly sad case.
Most of the tree of life is effectively arranged.
