Proximate causes of the red face of the bald uakari monkey
(2015)
In social species, such as primates, facial appearances transmit a variety of social signals. Although it is suggested that the intense red colour of the face of the bald uakari monkey might be an indicator of health, this ...
Aremicrobes fundamentally different than macroorganisms?
(2015)
This study reveals extensive phenotypic convergence based on the non-monophyly of genera and morphospecies of testate (shelled) amoebae. Using two independent markers, small subunit ribosomal DNA (ssu-rDNA) and mitochondrial ...
A highly infective plant-associated bacterium influences reproductive rates in pea aphids
(2016)
Pea aphids, A cyrthosiphon pisum, have the potential to increase reproduction as a defence against pathogens, though how frequently this occurs or how infection with live pathogens influences this response is not well ...
Tools to tipple
(2015)
African apes and humans share a genetic mutation that enables them to effectively metabolize ethanol. However, voluntary ethanol consumption in this evolutionary radiation is documented only in modern humans. Here, we ...
The unexpected survival of an ancient lineage of anseriformbirds into the Neogene of Australia
(2016)
Presbyornithids were the dominant birds in Palaeogene lacustrine assemblages, especially in the Northern Hemisphere, but are thought to have disappeared worldwide by the mid-Eocene. Now classified within Anseriformes ...
Isotopic evidence for residential mobility of farming communities during the transition to agriculture in Britain
(2016)
Development of agriculture is often assumed to be accompanied by a decline in residential mobility, and sedentism is frequently proposed to provide the basis for economic intensification, population growth and increasing ...
Temporal and phylogenetic evolution of the sauropod dinosaur body plan
(2016)
The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod ...
The cervical anatomy of Samotherium,an intermediate-necked giraffid
(2015)
Giraffidae are represented by many extinct species. The only two extant taxa possess diametrically contrasting cervical morphology, as the okapi is short-necked and the giraffe is exceptionally long-necked.Samotherium ...
The relationships of the Euparkeriidae and the rise of Archosauria
(2016)
For the first time, a phylogenetic analysis including all putative euparkeriid taxa is conducted, using a large data matrix analysed with maximum parsimony and Bayesian analysis. Using parsimony, the putative euparkeriidDorosuchus ...
Hybridization generates a hopeful monster
(2016)
Compared with other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes. Here we report observing one F1-hybrid individual that ...
