Assuming we have 1000 DNA residues at random, after time deltaT the sequences dffer from the original in 33% of the sites. Assuming that the sequence evolves under Jukes-Cantor, what is the expected number of substitutions per site? When deltaT becomes very large (infinity), how many sites will on average have the same nucleotide?

If you drill a hole through the centre of the earth to the other side and there was no chance that you would die, what would happen? Would you pop out the other side, or stay in the middle, taking gravity into account.
