New research shows that the loss of biodiversity can increase the risk of 'extinction cascades', where an initial species loss leads to a domino effect of further extinctions.
A new study on the timescale of plant evolution, led by the University of Bristol, has concluded that the first plants to colonise the Earth originated around 500 million years ago -- 100 million years earlier than previously thought.
Circumventing evolution in cell factories can pave the way for commercializing new biobased chemicals to large-scale.
Duplicate copies of a gene shared by male and female fruit flies have evolved to resolve competing demands between the sexes. New genetic analysis by researchers at the University of Chicago describes how these copies have evolved separate male- and female-specific functions that are crucial to reproduction and fertility.
In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs -- and offer an extraterrestrial source for mineral mining. But for Georgia Tech researcher Nicholas Hud, asteroids play an entirely different role: that of time capsules showing what molecules originally existed in our solar system. Having that information gives scientists the starting point they need to reconstruct the complex pathway that got life started on Earth.
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.
Scientists have identified a mineral signature for sites that are more likely to contain rare fossils that preserve evidence of soft tissue -- essential information to understanding ancient life.
Researchers have shown that the bacterial communities in termite guts came about through both inheritance and transfer between colonies.
Butterflies offer key insights into community ecology, how species originate and evolve, climate change and interactions between plants and insects. But a comprehensive map of how butterflies are related to each other has been lacking -- until now.
Predicting evolution remains difficult. Scientists from Utah State University, University of Sheffield, University of Connecticut, University of Notre Dame and Simon Frasier University studied evolution of cryptic body coloration and pattern in stick insects for insights.
