A further look at the 1858 Wallace-Darwin mail delivery question

Recent investigations have led to a conclusion that Alfred Russel Wallace probably mailed his ‘Ternate’ paper on natural selection to Darwin 1 month later than some have assumed, thus freeing Darwin from possible accusations of plagiarism. Further examination of the question suggests that this conclusion is premature because the evidence in favour of the later mailing date appears to be weaker than first considered. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, ●●, ●●–●●.
