TLDR
The geologic history and paleoclimate of the East African Great Lakes and the impact of these forces on the region's endemic cichlid flocks are reviewed.Abstract:
The cichlid fishes of the East African Great Lakes are the largest extant vertebrate radiation identified to date. These lakes and their surrounding waters support over 2,000 species of cichlid fish, many of which are descended from a single common ancestor within the past 10 Ma. The extraordinary East African cichlid diversity is intricately linked to the highly variable geologic and paleoclimatic history of this region. Greater than 10 Ma, the western arm of the East African rift system began to separate, thereby creating a series of rift basins that would come to contain several water bodies, including the extremely deep Lakes Tanganyika and Malawi. Uplifting associated with this rifting backponded many rivers and created the extremely large, but shallow Lake Victoria. Since their creation, the size, shape, and existence of these lakes have changed dramatically which has, in turn, significantly influenced the evolutionary history of the lakes' cichlids. This paper reviews the geologic history and paleoclimate of the East African Great Lakes and the impact of these forces on the region's endemic cichlid flocks.read more

TL;DR: It is demonstrated that hybridization between two divergent lineages facilitated this process by providing genetic variation that subsequently became recombined and sorted into many new species, indicating rapid and extensive adaptive radiation.

Ecology and Evolution of the African Great Lakes and Their Faunas
TL;DR: It is demonstrated that the African Great Lakes, because of excellent fossil archives, are a phenomenal setting to integrate micro- and macroevolution.

TL;DR: In this paper, the authors show that repeated cycles of lake expansion and contraction provide a push-pull mechanism for the isolation and combination of populations in Equatorial Africa that may contribute to the Late Pleistocene human biological variability suggested by the fossil and genetic 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.

Mantle dynamics, uplift of the Tibetan Plateau, and the Indian Monsoon
TL;DR: For example, Hou et al. as mentioned in this paper show that a small increase in the mean elevation of the Tibetan Plateau of 1000 m or more in a few million years is required by abrupt tectonic and environmental changes in Asia and the Indian Ocean.
Journal ArticleDOI
Hybridization and adaptive radiation
TL;DR: A concept that reconciles views of hybridization and ecological speciation theory is developed and adds a new twist to this debate, which predisposes colonizing populations to rapid adaptive diversification under disruptive or divergent selection.

TL;DR: An oxygen and carbon isotopic history based on analyses of benthonic and planktonic foraminifera in three overlapping subantarctic sections is presented for the last 55 m.y. as mentioned in this paper.

Flowering Plants: Evolution Above the Species Level
TL;DR: One of the most popular books now is the flowering plants evolution above the species level as discussed by the authors, but it is difficult to find the book in the book store around the city. And when you have found the store to buy the book, it will be so hurt when you run out of it.
