Researching the implications of downsizing the human species to better fit the earth.
Reptiles have always been spirit animals for The Incredible Shrinking Man research. From the shrinking iguanas of the Galapagos islands to the unsinkable Jesus gecko, reptiles often have something interesting to tell us about the consequences of size and the advantages of smallness. Cold-blooded reptile…
There are clear advantages to becoming very small. Micro-organisms gain access to new niches, acquire new food sources and avoid predation. They shrink towards abundance. Yet there are limiting factors to how small an animal can become including the disruption of thermoregulation or respiration, water…
Most of us presume growth of body length in vertebrates to be unidirectional, with organisms progressively increasing in body size as they become older. However, under challenging environmental conditions for some vertebrates body length shrinkage is also possible. This ability is called the Dehnel phenomenon.…
A study in Science shows that in a period of just 40 years two alpine bumblebee species (Bombus balteatus and Bombus sylvicola) rapidly evolved significantly shorter tongues. Short-tongued species are more generalist foragers, able to feed on many different types of flowers. They are replacing more specialised, long-tongued…
Livestock’s Long Shadow: Environmental Issues and Options, a 2006 report released by the Food and Agriculture Organisation, assesses the impact of the livestock sector on environmental challenges, along with potential technical and policy approaches to mitigation. The livestock sector poses serious challenges to the environment at every…
Fisherian runaway is a mechanism proposed by the mathematical and evolutionary biologist Ronald Fisher, to account for the evolution of exaggerated male ornamentation by persistent, directional female choice. When females are attracted to a certain trait within males, this trait over time gets over-emphasised because males with the trait…
