Exaptation-a missing term in the science of form
This work presents several examples of exaptation, indicating where a failure to concep- tualize such an idea limited the range of hypotheses previously available, and proposes a terminological solution to the problem of preadaptation. Expand
Environment and behavior of 2.5-million-year-old Bouri hominids.
The combined evidence suggests that behavioral changes associated with lithic technology and enhanced carnivory may have been coincident with the emergence of the Homo clade from Australopithecus afarensis in eastern Africa. Expand
A complete estimate of the phylogenetic relationships in Ruminantia: a dated species‐level supertree of the extant ruminants
The first complete estimate of the phylogenetic relationships among all 197 species of extant and recently extinct ruminants combining morphological, ethological and molecular information is presented, and the position of several taxa whose systematic positions have remained controversial in the past is unambiguously established. Expand
Paleoclimate and evolution, with emphasis on human origins
Addressing the relationship between climatic and biotic evolution, this work focuses on how climatic change during the last 15 million years - especially the last three million - has affected humanExpand
Mammals as a Key to Evolutionary Theory
Preliminary tests using the late Neogene records of the Americas and Africa suggest that major aspects of the Great American Interchange have parallels in the African record, as predicted by the habitat theory. Expand
African Homo erectus: old radiometric ages and young Oldowan assemblages in the Middle Awash Valley, Ethiopia.
Fossils and artifacts recovered from the middle Awash Valley of Ethiopia's Afar depression sample the Middle Pleistocene transition from Homo erectus to Homo sapiens, supporting the hypothesis that Middle Pleistsocene Oldowan assemblages represent a behavioral facies of the Acheulean industrial complex. Expand
Remains of Homo erectus from Bouri, Middle Awash, Ethiopia
Daka's resemblance to Asian counterparts indicates that the early African and Eurasian fossil hominids represent demes of a widespread palaeospecies and Daka's anatomical intermediacy between earlier and later African fossils provides evidence of evolutionary change. Expand
Some evidence of chronology and palaeoecology of Sterkfontein, Swartkrans and Kromdraai from the fossil Bovidae
Bovid fossil remains suggest a tentative chronology for the seven cave assemblages, from Sterkfontein, Swartkrans and Kromdraai, from which they are derived. They also suggest that, during the almostExpand
New fossils of Alcelaphini and Caprinae (Bovidae: Mammalia) from Awash, Ethiopia, and phylogenetic analysis of Alcelaphini
Alcelaphine antelopes comprise one of the most species-rich groups among the mammalian assemblages from the Middle Awash, Ethiopia, and in Africa as a whole. I describe a new genus and specExpand
