Although this has been traditionally linked to the appearance of stone tool-making, the alternative hypothesis of an earlier origin related to the freeing of the hands thanks to the advent of terrestrial bipedalism is also possible given the human-like intrinsic hand proportion found in australopiths.
This is possible thanks to human intrinsic manual proportions, i.e. a long thumb relative to the rest of the hand.
H1 is differentiated from the estimated intrinsic hand proportions of Au. afarensis in having a relatively long thumb ((Mc1 + PP1)/(Mc3 + PP3 + IP3)) (Rolian and Gordon, 2013; Almécija and Alba, 2014).
He respects the melodic line of a song and brings to everything he sings an intrinsic sense of balance and proportion.
The underlying rationale was that the canonical proportions intrinsic to the original works of art would elicit enhanced activity in areas mediating pleasure and, in particular, in the insula, the cortical region known to be involved in the feeling of emotion (see [11] [15]).
Burley now distinguishes a four-fold way in which something can be considered the first object of the intellect: by origin, by proportion, by intrinsic perfection, and by exclusion (primitate exclusionis) — the latter being the way a determinate object can be known by a certain faculty and by that faculty alone, excluding all others.
During intrinsic rhythm a significant proportion of acidified hearts developed spontaneous VT.
Exerting control to improve response precision might itself come at a cost a cost to attenuate a proportion of intrinsic neural noise.
By additionally using data on the relative sizes of different cluster types, we estimate the proportion of intrinsic gray matter connections that originate outside of the local network.
Intrinsic drug resistance in the proportion of clinical glioblastomas comprised of tumour stem cells has been suggested to play a key role in drug resistance in this disease, and the high CD133-positive content of these cells grown as monolayers may make them particularly relevant in preclinical drug screening programmes.
