http://physicsworld.com/cws/article/news/2014/sep/02/big-bang-ruled-out-as-origin-of-lithium-6 The hystory of BB nucleosynthesis is quite busy, Gamow et al. started postulating that all elements were originated in the BB nucleosynthesis process in the late 40s early 50s, it soon became quite evident through the work of Hoyle and others that it couldn't be so and the list was reduced to the light elements, slowly but steadily more elements fell off, now with Lithium ruled out, wich BB origin was a central prediction of BB nucleosynthesis, it seems it's down to twoydrogen and Helium. Actually what the nucleosynthesis would predict in principle is their proportion, approx. 1/4 in mass for Helium, wich is in basic accordance with its observed abundance. That the BB nucleosynthesis theory actually came up with this proportion(1/4) has been critiziced in the past by Hoyle(and others) who claimed that other theories without Big-bang, including his, also predicted it. Now BB nucleosynthesis used to be one of the three pillars of the Big-bang theory(the others being cosmological redshift and the CMB), is the ruling out of Lithium as originated in the Big-bang a big blow or just a scratch to the theory?
