Speciation, associated with the ability to spread from human to human and not only the capacity to cause TB, which is clearly much more ancient, would have resulted from the multiple events of human TB infections caused by M. canettii, interspersed with genetic reshuffling of M. canettii in the environment.
Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains.
Researchers have concluded that the love of music is not only a universal feature of the human species, found in every society known to anthropology, but is also deeply embedded in multiple structures of the human brain and is far more ancient than previously suspected.
As researchers conclude in the current issue of the journal Science, the love of music, that unslakable, unshakable, indescribable desire to sing and rejoice, rattle and roll, is not only a universal feature of the human species, found in every society known to anthropology, but is also deeply embedded in multiple structures of the human brain, and is far more ancient than previously suspected.
These findings suggested either a more ancient origin of UGT1A6 loss predating Felidae divergence, or perhaps more recent multiple UGT1A6 inactivations.
The modern soybean genome has experienced two "recent" whole-genome duplications (WGDs), and a more ancient triplication (Gamma WGT), and about 75% of the genes are present in multiple copies [ 41, 76].
More ancient clusters have been identified.
Unoriginality was much more ancient than I had originally suspected.
Many still more ancient delta lobes are now submerged.
But beneath that scaffolding lies something far more ancient.
