Tiktaalic

(4)

The big scientific news tonight is 'Tiktaalic,' a 375 million year old fossil which is described as a 'missing link.' Seems this ancient 'fish' has the head of a crocodile and upper limbs resembling those of modern mammals. Sucker could 'do pushups.' The lower skeleton apparently was mostly 'fishlike.' I am impressed.

But something seems to be missing here: a fossil which shows the transition between fishhead and crochead - something 'in between.' Will we ever find it? And if so, what other gaps in evolutionary 'theory' will that discovery then reveal? We can only guess.
