(15) Although most studies emphasise the similarity of the australopithecines to modern man, and suggest, therefore, that these creatures were bipedal tool-makers at least one form of which (Australopithecus africanus--"Homo habilis", "Homo africanus") was almost directly ancestral to man, a series of multivariate statistical studies of various postcranial fragments suggests other conclusions.
(16) The conservation of genomic organization, together with the high sequence homology, indicates that the mouse H+,K(+)-ATPase beta and Na+,K(+)-ATPase beta 2 subunit genes originated from a common ancestral gene.

(20) Our findings substantially increase the evidence indicative of a human-chimpanzee-gorilla clade with ancestral separations around 8 to 6 Myr ago.
Transmissible
Definition:
(a.) Capable of being transmitted from one to another; capable of being passed through any body or substance.
Example Sentences:
(1) The present results provide no evidence for a clear morphological substrate for electrotonic transmission in the somatic efferent portion of the primate oculomotor nucleus.
(2) It has been shown by LM and transmission electron microscopy that cells with blebs are viable and capable of mitotic activity.
(3) The presently available data allow us to draw the following conclusions: 1) G proteins play a mediatory role in the transmission of the signal(s) generated upon receptor occupancy that leads to the observed cytoskeletal changes.
(4) The transmission of alcoholism and its effects are thereby lessened for future generations of children of alcoholics.
(5) Transmission electron microscopy demonstrated that these blebs were devoid of organelles and microvilli; scanning electron microscopy revealed that the blebs were highly wrinkled and more numerous than were the projections observed in tissue from animals treated with testosterone alone, or in tissue from unoperated controls.
(6) The intent of this study was to investigate, by three-dimensional photoelastic analysis, the stress transmission that occurs with four commonly used retentive systems.
(7) Intoxicating concentrations of ethanol also inhibit excitatory synaptic transmission mediated by N-methyl-D-aspartate receptors in hippocampal slices from adult rodents.
(8) These results indicate that both racemic and L-baclofen inhibit trigeminal transmission in man, probably because they interfere with excitatory transmission through the interneurons of the lateral reticular formation.
(9) Substance P, a potent vasodilating peptide, seems to be released from trigeminal nerve endings in response to nervous stimulation and is involved in the transmission of painful stimuli within the periphery.
