Homo floresiensis-like fossils from the early Middle Pleistocene of Flores.
TLDR
This work describes hominin fossils excavated in 2014 from an early Middle Pleistocene site (Mata Menge) in the So'a Basin of central Flores and suggests that hominins on Flores had acquired extremely small body size and other morphological traits specific to H. floresiensis at an unexpectedly early time.
Insights on the Early Pleistocene Hominin Population of the Guadix-Baza Depression (SE Spain) and a Review on the Ecology of the First Peopling of Europe
The chronology and environmental context of the first hominin dispersal in Europe have been subject to debate and controversy. The oldest settlements in Eurasia (e.g., Dmanisi, ∼1.8 Ma) suggest a
Plastic pioneers: Hominin biogeography east of the Movius Line during the Pleistocene
Earliest known hominin activity in the Philippines by 709 thousand years ago
TLDR
Stone tools and a disarticulated and butchered skeleton of Rhinoceros philippinensis, found in a securely dated stratigraphic context, indicate the presence of an unknown hominin population in the Philippines as early as 709 thousand years ago, which pushes back the proven period of colonization of the Philippines by hundreds of thousands of years.
A new rhinoceros clade from the Pleistocene of Asia sheds light on mammal dispersals to the Philippines
TLDR
The phylogenetic results strongly suggest an island-hopping dispersal for Nesorhinus, from the Asian mainland towards Luzon via Taiwan by the Late Miocene or later, and Pleistocene dispersals for representatives of Rhinoceros.
Human Palaeoecological Interactions and Owl Roosting at Tron Bon Lei, Alor Island, Eastern Indonesia
ABSTRACT We report on tetrapod (Reptilia, Amphibia, Mammalia, Aves) vertebrates recovered during excavations at Tron Bon Lei rockshelter on the south coast of Alor Island, eastern Indonesia. These
Homo sapiens in the Eastern Asian Late Pleistocene
TLDR
The study reveals that despite having similar chronologies, not all the samples present the same suite of derived traits and may reflect complex demographic dynamics with several migrations and dispersals and/or a degree of population substructure similar to that described for the African continent.
Quaternary vertebrate faunas from Sumba, Indonesia: implications for Wallacean biogeography and evolution
TLDR
This new baseline for reconstructing Wallacean faunal histories reveals that Sumba's Quaternary vertebrate fauna was comparable in diversity and composition to theQuaternary fauna of Flores, suggesting that similar assemblages may have characterized QuaternARY terrestrial ecosystems on many or all of the larger Lesser Sunda Islands.

TLDR
The evidence supports the hypothesis that Homo floresiensis is a late-surviving species of early Homo with its closest morphological affinities to early African pre-erectus/ergaster hominins, and requires fundamental paradigm changes in the understanding of human evolution.
Homo floresiensis: microcephalic, pygmoid, Australopithecus, or Homo?
Archaeology and age of a new hominin from Flores in eastern Indonesia
TLDR
Dating by radiocarbon, luminescence, uranium-series and electron spin resonance methods indicates that H. floresiensis existed from before 38,000 years ago (kyr) until at least 18 kyr, and originated from an early dispersal of Homo erectus that reached Flores and then survived on this island refuge until relatively recently.

The fellowship of the hobbit: the fauna surrounding Homo floresiensis
TLDR
Evidence reviewed herein shows that features exhibited by H. floresiensis can be explained by existing models of insular evolution and followed evolutionary pathways similar to those of the other terrestrial vertebrates inhabiting Pleistocene Flores.
Genetic, physiologic and ecogeographic factors contributing to variation in Homo sapiens: Homo floresiensis reconsidered
TLDR
Substantial support is found for the hypothesis that the remains of Homo floresiensis represent a variant of H. sapiens possessing a combined growth hormone–insulin‐like growth factor I axis modification and mutation of the MCPH gene family.
Dragon's Paradise Lost: Palaeobiogeography, Evolution and Extinction of the Largest-Ever Terrestrial Lizards (Varanidae)
TLDR
The palaeobiogeography of Neogene giant varanids is reconstructed and a new (unnamed) species from the island of Timor is identified, rejecting the long-held perception that V. komodoensis became a giant because of insular evolution or as a specialist hunter of pygmy Stegodon.
Hominins on Flores, Indonesia, by one million years ago
TLDR
It is shown using 40Ar/39Ar dating that an ignimbrite overlying the artefact layers at Wolo Sege was erupted 1.02 ± Myr ago, providing a new minimum age for hominins on Flores, which predates the disappearance from the Soa Basin of ‘pygmy’ Stegodon sondaari and Geochelone spp.
Macaque evolution and dispersal in insular south-east Asia
TLDR
A new perspective of macaque dispersal through the Indonesian archipelago is proposed, which takes into account sea-level changes, as well as latitudinal and altitudinal rainforest shifts following climatic cycles during the Quaternary.
