Populations of nations, regions, continents, islands, or cities, however, are rarely closed in the same way. If the assumption of a closed population is relaxed, in- and out-migration can increase and decrease population size in the same way as do births and deaths; thus, the population (...
Human evolution, the process by which human beings developed on Earth from now-extinct primates. The only extant members of the human tribe, Hominini, belong to the species Homo sapiens. The exact nature of the evolutionary relationships between modern h
Full size image We then compared this new country classification (according to the individual countries’ sex-search profile, Supplementary Table S7 and Supplementary Methods S1) with our previous identification based only on the proportion of the population that self-identified as Christian, Muslim or...
Most intensive human activities occur in lowlands. However, sporadic reports indicate that human activities are expanding in some Asian highlands. Here we investigate the expansions of human activities in highlands and their effects over Asia from 2000 to 2020 by combining earth observation data and s...
limited utilization of remote sensing technology acquiring high-resolution earth observed imagery in disease prediction and early warning systems; 4. absence of consideration of the impacts of climate change on various diseases has limited the focus primarily to vector-borne pathogens and research conduc...
Before eating, compared to our ancestors, modern human teeth, jaws and faces have gotten smaller relative to overall skull(头盖骨) size because of making food easier to chew, especially from cooking.Cooking food was one of the biggest changes in human history, researchers believe it could have...
“throwing sticks were efficient weapons and should not be underestimated when compared to spear and arrow damage” (Bordes,2020), they were nevertheless “more adapted to use in open woodland and dry savanna without too many obstacles and on levelled ground” (Bordes,2020). In particular, ...
That is, compared to mere contact with nature and having a nice time outside, intimate contact with nature (e.g., perhaps through actions as simple as walking barefoot; see [74,87]) and contact that promotes meaningful interdependence with nature should most strongly lead to greater nature ...
The connotation of beautiful human settlements, beautiful human settlements refers to the harmonious development of human–Earth relationship within a certain time and geographic space scale, including not only the overall beauty of the human settlements, but also the internal elements and subsystems, ...
