All That We Are is Contained in 5% of Our DNA.

I’ve always found it fascinating just how much commonality there is between us and many other life forms on earth. The explanation is quite simple: certain biological features are the most suited to the world that we live in and thus give the highest chance of survival and procreation. Still even with that fact in mind I still marvel at how much in common we have with even the most bizarre creatures and it gets even more intriguing when you go down to the DNA level. It’s been well known for a long time that we’re genetically very similar to primates to the tune of something like 95%.

One of my favorite astrophysicists (yes I have several)  Neil DeGrasse Tyson made a fascinating point about that small genetic difference (skip to 7:35, although the first point is amazing too):

All we are, all the stuff that differentiates us from the great apes is contained in that small difference of DNA. The idea then that another form of intelligent life could be that different from us again really is fascinatingly disturbing as from their point of view we’d be little above cattle to them. You’d hope though that past a certain level of intelligence you’d have some respect for any form of life (like many humans do) but our history has shown how even intelligent species can regard their own as beneath them.

Now if you’ll excuse me I’ll just go and work my way through this existential crisis I’m having.

God of the Gaps.

I’ve always been fascinated by people who are incredibly smart and religious. To me they seem to be diametrically opposed as education goes up the evidence for God’s existence starts to come under question, usually to the point of pushing people to be either agnostic or atheist. For me it was mostly my distaste for the study of religion (I found it boring) and the ham fisted approach that my science teacher had to reconciling the Anglican school teachings with actual science.

For those both gifted and religious the most common explanation I get is the things we can’t yet explain come under the purview of a god or the God. I watched a video of an interview with Neil DeGrasse Tyson recently that sums up why that approach is fundamentally flawed:

Taken to its logical extreme, as in as our knowledge approaches the limit of all we can ever know, God then can only exist in infinitesimally smaller gaps. Logically then the belief in such an entity seems irrational as God is then just an ever shrinking pocket of ignorance. You can of course neatly sidestep this argument by saying you fully believe in your faith regardless of what science says and I’ll neatly sidestep any argument with you on the matter because I’m sure neither of us will walk away happy from it 😉
