The taxonomic status of Neanderthals lies at the center modern human origins debate. Proponents single-origin model often view this group as a distinct species with little or no contribution to evolution humans. Adherents regional continuity consider subspecies population Homo sapiens , which contributed significantly early Europeans. Paleontologists generally agree that fossil should be equivalent extant ones in amount their morphological variation. Recognition therefore hinges on analogy...
The assembly of Africa's iconic C4 grassland ecosystems is central to evolutionary interpretations many mammal lineages, including hominins. grasses are thought have become ecologically dominant in Africa only after 10 million years ago (Ma). However, paleobotanical records older than Ma sparse, limiting assessment the timing and nature biomass expansion. This study uses a multiproxy design document vegetation structure from nine Early Miocene site complexes across eastern Africa. Results...
Living hominoids are distinguished by upright torsos and versatile locomotion. It is hypothesized that these features evolved for feeding on fruit from terminal branches in forests. To investigate the evolutionary context of hominoid adaptive origins, we analyzed multiple paleoenvironmental proxies conjunction with fossils Moroto II site Uganda. The data indicate seasonally dry woodlands earliest evidence abundant C4 grasses Africa based a confirmed age 21 million years ago (Ma). We...

Abstract Australopithecus sediba has been hypothesized to be a close relative of the genus Homo. Here we show that MH1, type specimen A. , was not optimized produce high molar bite force and appears have limited in its ability consume foods were mechanically challenging eat. Dental microwear data previously interpreted as indicating consumed hard foods, so our findings illustrate mechanical are essential if one aims reconstruct relatively complete picture feeding adaptations extinct...
ABSTRACT Western gorillas ( Gorilla gorilla ) are known to climb significantly more often than eastern beringei ), a behavioral distinction attributable major differences in their respective habitats (i.e., highland vs. lowland). Genetic evidence suggests that the lineages leading these taxa began diverging from one another between approximately 1 and 3 million years ago. Thus, offer special opportunity examine degree which morphology of recently diverged may be “fine‐tuned” differing...
The origin of hominins found on the remote Indonesian island Flores remains highly contentious. These specimens may represent a new hominin species, Homo floresiensis, descended from local population erectus or an earlier (pre-H. erectus) migration small-bodied and small-brained out Africa. Alternatively, some workers suggest that all recovered Liang Bua are pathological members modern human population. Pathological conditions proposed to explain their documented anatomical features include...
ABSTRACT ‘Crocodylus’ pigotti is a relatively small crocodylid from the Miocene of Rusinga Island in Lake Victoria, Kenya. Known only one complete skull and limited, fragmentary, referred material, lacks detailed description. Moreover, recent analyses have shown to be an osteolaemine crocodylid, more closely related extant dwarf crocodiles (Osteolaemus) than true Crocodylus. Here, we describe numerous new remains recovered localities within Fossil Bed Member Hiwegi Formation at Kaswanga...
Abstract We describe two new osteolaemine crocodylids from the Early and early Middle Miocene of Kenya: Kinyang mabokoensis tax. nov. (Maboko, 15 Ma) tchernovi (Karungu Loperot, 18 Ma). Additional material referable to is known Chianda Moruorot. The skull was broad dorsoventrally deep, genus can be diagnosed based on combined presence a partial overbite, subdivided fossa for lateral collateral ligament surangular, maxilla with no more than 13 alveoli. Phylogenetic analyses morphological...
Early Miocene outcrops near Karungu, Western Kenya, preserve a range of fluvio-lacustrine, lowland landscapes that contain abundant fossils terrestrial and aquatic vertebrates. Primates are notably rare among these remains, although nearby early strata on Rusinga Island rich assemblage fossilized catarrhines strepsirrhines. To explore possible environmental controls the occurrence primates, we performed deep-time Critical Zone (DTCZ) reconstruction focused floodplain paleosols at Ngira...
Early Miocene deposits on Rusinga Island (Lake Victoria, Kenya) contain an abundance of faunal and floral remains.Despite the attention that has historically been given to early fauna from Island, little fossil floras date no studies have described leaf morphotypes Island.Here, we present a morphotype catalog leaves collected Grit Member Hiwegi Formation Island.We describe 14 morphotypes, comprised 12 dicotyledonous angiosperms two monocotyledonous angiosperms, as well distinct angiosperm...
The proliferation of geometric morphometrics (GM) in biological anthropology and more broadly throughout the sciences has resulted a multitude studies that adopt landmark-based approaches for addressing variety questions evolutionary morphology. In some cases, particularly realm systematics, fit between research question analytical design is quite good. Functional-adaptive studies, however, do not readily conform to methods available GM toolkit. symposium organized by Terhune Cooke entitled...
