New neutrino oscillation data from T2K continues to strongly favor a normal mass ordering over an inverted mass ordering. Cosmology based bounds on neutrino masses also favor a normal mass ordering. Direct measurements of neutrino mass are not discerning enough to distinguish between the possibilities.
There is a more mild preference for θ23 value in the upper octant. This parameter is roughly 49°±1° in the upper octant and 41º ±1°in the lower octant.
Illustration from here.
Non-zero CP violation in neutrino oscillation is preferred by more than two sigma, but estimates of the amount of CP violation in neutrino oscillation are very imprecise.

Diversity and Evolution of Archaic Eastern Asian Hominins:
A Synthetic Model of the Fossil and Genetic Records
ABSTRACT
With the discoveries of new hominin fossils from historically well-studied as well as poorly sampled regions,
and thanks to great advances in paleogenetic studies, Asian paleoanthropology has now entered a new phase of
research. In particular, fossil discoveries from insular Southeast Asia demonstrate unique pathways of hominin
evolution that contrast markedly with the continental pattern, while new fossils from the latter region reveal the
hitherto unrecognized great range of morphological diversity that characterized pre-sapiens Asian Homo. Further-
more, extensive analyses of Denisovan genomes offer a new framework in which the existing Asian fossil record
can be interpreted. In this paper, we review these developments by first summarizing our current knowledge
about each of the major hominin fossils from eastern Asia. We then present a large scaled craniometric analysis
to determine the basic pattern of spatiotemporal variation of eastern Asian hominins from the late Calabrian (late
Early Pleistocene) through the Late Pleistocene. Based on this, we discuss four issues: the question of H. erectus
evolutionary continuity on Java during the Pleistocene, evidence for regional continuity vs. discontinuity in conti-
nental East Asian archaic Homo, which of the existing fossils from eastern Asia represent Denisovans, and whether
there is fossil evidence for Denisovans across the Sunda Shelf of Southeast Asia, implying an oversea distribution

@neo You might find a recent post by John Hawks enlightening. https://johnhawks.net/weblog/what-do-we-know-about-the-ancestry-of-homo-erectus/
ReplyDelete“It is quite possible that this population represents gene flow between Asian H. erectus, and possibly H. antecessor, H. bodoensis, and/or early Neanderthals, supporting the idea of continuity with hybridization as a major force shaping human evolution in eastern Asia during the late Middle and early Late Pleistocene.”—Xiujie Wu and Christopher Bae
ReplyDeleteisn't that multi region origin first Asian Hominin ?
Give it up on the whole multi-regional thing. Modern humans are predominantly (more than 95% in all but a few relict island SE Asia/Papuan populations and in all cases more than 90%) from a common Out of Africa origin. Modest introgression from archaic hominins is not a multi-regional hypothesis scenario.
