[Brace yourself, this is a long read]
It seems like ever since mid-2013, not a month goes by without hearing about what I would call "PigChimpMan theory" of human evolution. This "theory" has been lurking around for a while in its own obscure corner of the internet, but it initially came to the attention of a wider online audience via PhysOrg back in July 2013. However, the idea was well and truly launched like a dysfunctional bottle rocket in November 2013 into the mainstream when it was publicised by that bastion of rigorous science journalism, the Daily Mail. Subsequently, it had spread like a pandemic swine flu across other media outlets.
(BTW, I'm not going to link to those pages directly and give them the hits, but if you wish to see them, they can easily be found via a quick Google search)
But we're not here to talk about that, as the ridiculousness of that theory has been thoroughly addressed by +PZ Myers
