The broiler chicken as a signal of a human reconfigured biosphere
The broiler chicken as a signal of a human reconfigured biosphere
Changing patterns of human resource use and food consumption have profoundly impacted the Earth's biosphere. Until now, no individual taxa have been suggested as distinct and characteristic new morphospecies representing this change. Here we show that the domestic broiler chicken is one such potential marker. Human-directed changes in breeding, diet and farming practices demonstrate at least a doubling in body size from the late medieval period to the present in domesticated chickens, and an up to fivefold increase in body mass since the mid-twentieth century. Moreover, the skeletal morphol...

Download scientific diagram | Estimations of the total global biomass (organically bound carbon) regarding humans, wild terrestrial mammals and large domesticated animals (livestock) for the years 1900 and 2000 (upper charts). The lower chart indicates the ratio of species diversity (number of species) of extant terrestrial mammals as well as number of species of terrestrial mammalian ungulates that have been domesticated (livestock).
