Researchers at Columbia University develop a new model considering life history traits' impact on mutation rates, finding that the molecular clock wobbles as it evolves. This leads to revised estimates of the human-chimp split time, supporting a mutational slowdown and reconciling genetic and paleontological data.
Researchers used COMPADRE database to study 418 plant species, finding half of variation in life history is caused by growth rate and reproductive strategy. The study suggests understanding these patterns can help predict population persistence, extinction, and diversification.
A new family of glycerol transporters has been discovered in insects, which may have enabled their dominance on Earth. The transporters, called entomoglyceroporins, have a higher ability for glycerol transport than other channels, suggesting they played a key role in insects' success.
A team of researchers used DNA from frozen and dried specimens to analyze a dataset of 39 genomes, defining seven new suborders and the 'trunk' of the Agaricales tree. The study provides a framework for testing hypotheses of mushroom evolution and highlights the importance of fungaria as scientific resources.
Researchers at Arizona State University are working with the University of Tennessee's Anthropological Research Facility to analyze human remains using isotopic analysis.

Researchers De Paepe and Taddei found that bacteriophages exhibit life history trade-offs between survival and reproduction, with rapid reproducers suffering higher casualties outside the host. Two physical parameters account for most of the observed variation in survival, suggesting a fundamental property of evolving entities.
Researchers found that salmonid fish gene expression is controlled by a few major genes and can predict their future lifestyle. This study reveals how programs of gene expression shape different developmental outcomes in these fish, which exhibit exceptional life-history variation.
Evolutionary biologist Vermeij suggests that certain traits, such as photosynthesis and human language, are so advantageous that they would reappear in different forms. Many unique innovations are ancient, while repeated ones are known from few specimens due to species extinction.
A new study confirms that evolution selectively influences life history traits affecting fitness, such as age at reproduction and senescence. Guppy populations show no postreproductive lifespan variation, contrary to expectations, suggesting this aspect of life history may be randomly determined.
