I can answer a wide variety of questions about general evolution or ecology. I can identify wild reptiles and amphibians based on moderate to high quality descriptions or photos, and I can provide information about species' habitats, behaviors, ranges, etc. | |

I can answer questions about evolutionary mechanisms and theory, including genetic drift, mutation, natural selection, etc. I also can clear up misconceptions about evolution as it's sometimes talked about by those not well-versed in the subject (e.g., some politicians and many religious fundamentalists). |
Hi Geoff, First off, evolution, as thought of and discussed by most biologists, generally refers to ‘microevolution,’ which can be defined as: the change in allele (variants of proteins) frequencies
