Today (1st July) is Natural Selection Day 2022!

Well, not really, but on this day in 1858, Charles Darwin and Alfred Russel Wallace's independently originated identical theories of evolution by natural selection, were announced at a meeting of the Linnean Society of London. Their joint paper on the subject was published a month later, revolutionising the field of biology and shaking the foundations of religious belief (and, no, the paper was not ignored as many have said, look out for a paper I will be publishing soon!). Fifteen months later the idea was elaborated and popularised in Darwin's book Origin of Species, and the rest is history. Next year, 2023, sees the 200th anniversary of Wallace's birth, which will be an excellent opportunity for science education and public engagement - let's not miss it! For more information see and
