R Script of analysis of megafauna-dispersed fruit species

This data supports
the analysis of the publication: van Zonneveld M, Larranaga N, Blonder B,
Coradin L, Hormaza JI, Hunter D. Human diets drive range expansion of
megafauna-dispersed fruit species (2018) PNAS. 10.1073/pnas.1718045115. The R script and
the data can be used to recalculate the analysis of this paper. The analysis
consists of geographic and environmental ranges of 130 fruit species from three
diet groups:

·
30 fruit-producing species that were part of megafauna diets but that did <i>not</i> became
part of human diets. These are fruit species reported to have been consumed by
and dispersed by giant sloths and other extinct megafauna in Central and South
America.

·
61 wild
fruit-producing species that have been part of both human and megafauna diets
in Central and South America.

·
39
cultivated fruit-producing species that have been part of both human and
megafauna diets in Central and South America.
