Microbrachius dicki is the first-known animal to stop reproducing by spawning and instead mate by having sex.

Or Micro Dick as he is affectionally known…

and also [pedant] ‘tarmac’ isn’t a scots invention. MacAdam only invented the ‘mac’ bit that later was used in in tarmac, it was a welshman (Edgar Purnell Hooley) who patented binding a macadam surface with tar 80 years later (although a guy in monarch actually just beat him to it). The confusion stems from MacAdam’s nickname being ‘Tar MacAdam’ because aside from his road building he owned a tar factory in Muirkirk that made waterproofed ropes but he never used tar for his road building [/pedant]

It took another few million years for copulation to make a come-back

Ah, so the Scots invented marriage too ?
