Discovering who was a leader, or even if leaders existed, from the ruins of archaeological sites is difficult, but now a team of archaeologists and biological anthropologists, using a powerful combination of radiocarbon dating and ancient DNA, have shown that a matrilineal dynasty likely ruled Pueblo Bonito in New Mexico for more than 300 years.

Nose form was shaped by climate
Big, small, broad, narrow, long or short, turned up, pug, hooked, bulbous or prominent, humans inherit their nose shape from their parents, but ultimately, the shape of someone's nose and that of their parents was formed by a long process of adaptation to our local climate, according to an international team of researchers.

Food webs entangle humans, animals, crops and the environment
Reconstructed food webs from the Ancestral Puebloan southwestern United States show the complexity and interconnectedness of humans, other animals, crops and the environment, in an area of uncertain climate and resources, according to researchers, who think climate change and human decisions then, may shed light on future human choices.

Maize from El Gigante Rock Shelter shows early transition to staple crop
Mid-summer corn on the cob is everywhere, but where did it all come from and how did it get to be the big, sweet, yellow ears we eat today? Some of the answers come from carbon dating ancient maize and other organic material from the El Gigante rock shelter in Honduras, according to a team of anthropologists who show that 4,300 years ago maize was sufficiently domesticated to serve as a staple crop in the Honduran highlands.

Understanding roots opens students to science, diversity
Focusing science education on students through genetic and genealogical studies may be the way to increase minorities in the pipeline and engage students who would otherwise deem science too hard or too uninteresting, according to a Penn State anthropologist

Blacks, Hispanics less likely to drink tap water, more likely to buy bottled
Black and Hispanic U.S. adults are half as likely as whites to drink tap water and more than twice as likely to drink bottled water, according to a recent Penn State analysis. The findings support past research that indicates that minorities and more vulnerable populations have a higher distrust of tap water in America, and that those who instead consume bottled water are at greater risk of health issues and financial burdens.

Loss of mastodons aided domestication of pumpkins, squash
If Pleistocene megafauna -- mastodons, mammoths, giant sloths and others -- had not become extinct, humans might not be eating pumpkin pie and squash for the holidays, according to an international team of anthropologists.

Where there's smoke and a mutation there may be an evolutionary edge for humans
