How are amphibians different from all other classes of vertebrates? What kind of amphibians have backbones? What characteristics are common to both birds and reptiles? What do amphibians look like when they are born? What do amphibians and humans have in common? What makes marine reptiles distinc...
In all subspecies, there are subpopulations and gradual clinal changes so that it is difficult to define the characteristics of that subspecies without looking at a broad geographic sample. In addition, the distribution of Canada Geese is dynamic, changing frequently and rapidly in response to climat...

it seems reasonable to conclude that there were differences between anatomically modern human and Neanderthal brains, and that these underlie at least some of the characteristics of our lineage42. We want to emphasize that such recent differences are likely to be subtle when compared to those after...
Using characteristics of the faunal assemblage I assess whether people hunted marine birds or ENSO created a subsistence opportunity for people to either scavenge a catastrophic assemblage or collect a community of vulnerable birds prior to the debris flow. I present avian skeletal part frequencies, ...
It acts as a reservoir for biological and genetic diver- sity, purifies the air and water, and provides habitat for wildlife, including birds, mammals, insects, and microorganisms. The boreal biome also provides food and renewable raw materials for human use; it is a major source of softwood...
