| Large mammals are genetically less variable? | |
| 1985 Evolution (39): 210-212 | |
Estimates of genetic variability, based on electrophoretic studies, indicate a large disparity among organisms within various taxonomic assemblages. One hypothesis forwarded to account for some of these differences suggests that large, mobile animals generally have lower levles of genetic variability than smaller, less mobile ones. Theses authors proposed following logically Levin's work, that larger animals perceive their environment as fine grained or more predictable. An organism's perception of its environment as fine grained suggests a dampening of internal metabolic responses due to environmental perturbations. |
