Inferences regarding the diet of extinct hominins: structural and functional trends in dental and mandibular morphology within the hominin clade.
This contribution investigates the evolution of diet in the Pan-Homo and hominin clades. It does this by focusing on 12 variables (nine dental and three mandibular) for which data are available about extant chimpanzees, modern humans and most extinct hominins. Previous analyses of this type have approached the interpretation of dental and gnathic function by focusing on the identification of th...
متن کاملColloquium paper: how many tree species are there in the Amazon and how many of them will go extinct?
New roads, agricultural projects, logging, and mining are claiming an ever greater area of once-pristine Amazonian forest. The Millennium Ecosystems Assessment (MA) forecasts the extinction of a large fraction of Amazonian tree species based on projected loss of forest cover over the next several decades. How accurate are these estimates of extinction rates? We use neutral theory to estimate th...
متن کاملPaleogenomics of Archaic Hominins
In order to understand the genetic basis for the evolutionary success of modern humans, it is necessary to compare their genetic makeup to that of closely related species. Unfortunately, our closest living relatives, the chimpanzees, are evolutionarily quite distant. With the advent of ancient DNA study and more recently paleogenomics - the study of the genomes of ancient organisms - it has bec...
متن کاملA picture falls under many categories: How ancient mathematical marks became extinct
The development of mathematical marking conventions from prehistory to the present is characterized by a trend from conventions with more iconic relationships to concrete structures of the physical world (such as more pictorial ancient land surveying marks) to marking systems with less-iconic relationships to physical structures (that represent numbers, operations, infinity, and other more abst...
متن کاملBoomerang returns unexpectedly
Experimental study of the anisotropy in the cosmic microwave background (CMB) is gathering momentum. The eagerly awaited Boomerang results have lived up to expectations. They provide convincing evidence in favor of the standard paradigm: the Universe is close to flat and with primordial fluctuations which are redolent of inflation. Further scrutiny reveals something even more exciting however –...
