With an average brain weight of 1,330grams (Tobias 1971), the human species has the largest absolute brain size within the primate order, but is actually dwarfed by elephants and some of the Cetacea, where brain weight can exceed 7,500grams. Of course, the body weights are very much ...
For microbes, the fuzziness of the species concept makes it difficult to even define what a population is [11••,12•]. Population structure then poses a particular challenge to microbial population genetics [13]. Nevertheless, microbial populations are expected to be especially prone to ...

Species that have been translocated and otherwise manipulated by humans may show patterns of population structure that reflect those interactions. At the same time, natural processes shape populations, including behavioural characteristics like dispersal
The current status of species and their ability to persist locally can be first explored by examining the evolutionary processes faced with contemporary environmental change [6]. By investigating population genetic diversity and structure, population genetics contributes towards disentangling the mechanisms th...
