TLDR
Faunal evidence of the Turkana Basin of Kenya corroborates conclusions derived from other lines of evidence, but raises new questions as discussed by the authors, as it is not all parts of this basin responded in the same way to climate change.About:

Journal ArticleDOI
Evolution of Grasses and Grassland Ecosystems
TL;DR: The evolution and subsequent ecological expansion of grasses (Poaceae) since the Late Cretaceous have resulted in the establishment of one of Earth's dominant biomes, the temperate and tropical grasslands, at the expense of forests as mentioned in this paper.

TL;DR: Although the Early Pliocene Afar included a range of environments, and the local environment at Aramis and its vicinity ranged from forests to wooded grasslands, the integration of available physical and biological evidence establishes Ar.

The Diets of Early Hominins
Peter S. Ungar,Matt Sponheimer +1 more
TL;DR: Diet changes are considered key events in human evolution and traditional ideas have held; others, such as an increasing reliance on hard-object feeding and a dichotomy between Australopithecus and Paranthropus, have been challenged.

Biogeography of the grasses (Poaceae): a phylogenetic approach to reveal evolutionary history in geographical space and geological time
Yanis Bouchenak-Khelladi,Yanis Bouchenak-Khelladi,G. Anthony Verboom,Vincent Savolainen,Vincent Savolainen,Trevor R. Hodkinson +5 more
TL;DR: A dated phylogenetic tree based on combined plastid DNA sequences and a comprehensive sample of Poaceae and an additional tree using a supermatrix of morphological and molecular data that included all 800 grass genera so that ancestral biogeography and ecological habitats could be inferred.
Journal ArticleDOI
Mammalian Response to Cenozoic Climatic Change
TL;DR: This work has shown that shared life history traits and evolutionary history allow us to generalize about mammalian response to climatic change above the species level, and these generalizations provide the insights into the complexity of mammalian response.

TL;DR: Global croplands, pastures, plantations, and urban areas have expanded in recent decades, accompanied by large increases in energy, water, and fertilizer consumption, along with considerable losses of biodiversity.

Trends, Rhythms, and Aberrations in Global Climate 65 Ma to Present
TL;DR: This work focuses primarily on the periodic and anomalous components of variability over the early portion of this era, as constrained by the latest generation of deep-sea isotope records.

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.

Plio-Pleistocene African Climate
TL;DR: Major steps in the evolution of African hominids and other vertebrates are coincident with shifts to more arid, open conditions near 2.8 Ma, suggesting that some Pliocene (Plio)-Pleistocene speciation events may have been climatically mediated.
