Journal ArticleDOI
Global vegetation change through the Miocene/Pliocene boundary
Thure E. Cerling,John Harris,Bruce J. MacFadden,Meave G. Leakey,Jay Quade,Véra Eisenmann,James R. Ehleringer +6 more
TL;DR: For example, this paper found that between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia, Africa, North America and South America.
Journal ArticleDOI
New four-million-year-old hominid species from Kanapoi and Allia Bay, Kenya
TL;DR: The mosaic of primitive and derived features shows this species to be a possible ancestor to Australopithecus afarensis and suggests that Ardipithecus ramidus is a sister species to this and all later hominids.
Journal ArticleDOI
Growth processes in teeth distinguish modern humans from Homo erectus and earlier hominins
Christopher Dean,Meave G. Leakey,Donald J. Reid,Friedemann Schrenk,Gary T. Schwartz,Chris Stringer,Alan Walker +6 more
TL;DR: Differences in enamel growth are reported that show the earliest fossils attributed to Homo do not resemble modern humans in their development, and it seems likely that truly modern dental development emerged relatively late in human evolution.
Journal ArticleDOI
New hominin genus from eastern Africa shows diverse middle Pliocene lineages.
Meave G. Leakey,Fred Spoor,Francis H. Brown,Patrick N. Gathogo,Christopher Kiarie,Louise N. Leakey,Ian McDougall +6 more
TL;DR: New fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis point to an early diet-driven adaptive radiation, provide new insight on the association of hominin craniodental features, and have implications for the understanding of Plio–Pleistocene hom inin phylogeny.
Journal ArticleDOI
Inactivation of CMP-N-acetylneuraminic acid hydroxylase occurred prior to brain expansion during human evolution
Hsun Hua Chou,Toshiyuki Hayakawa,Sandra Diaz,Matthias Krings,Etty Indriati,Meave G. Leakey,Svante Pääbo,Yoko Satta,Naoyuki Takahata,Ajit Varki +9 more
TL;DR: The studies indicate that the CMAH gene was inactivated shortly before the time when brain expansion began in humankind's ancestry, ≈2.1–2.2 mya.
