The Bristol Palaeobiology Research Group explores all aspects of the history of the biosphere. From macroevolution to mass extinctions, we learn from the deep past to inform our predictions of the ...

This important study introduces an approach to discovering antibiotic resistance determinants by leveraging diverse susceptibility profiles among related mycobacterial species, with particular ...

Humans really do rule the world. We took over fast and far, more than any other wild vertebrates. We inhabit nearly every corner of the world, and can thrive in deserts, tropical rainforests and even ...

This event is closed to the public. During the Holocene the scale and complexity of human societies increased dramatically. Generations of scholars have proposed different theories explaining this ...

Some 445 million years ago, life on Earth was forever changed. During the geological blink of an eye, glaciers formed over the supercontinent Gondwana, drying out many of the vast, shallow seas like a ...

Understanding the relationship between macro- and microevolutionary processes and their delimitation remains a challenge. This review focuses on the role of chromosomal rearrangements in plant ...

Legend has it that physicist Ernest Rutherford once dismissed all sciences other than physics as mere “stamp collecting.” (Whether he actually said it is a matter of some debate.) But we now live in ...

This work shows that resistance profiles to a variety of drugs are variable between different mycobacterial species and are not correlated with growth rate or intrabacterial compound concentration (at ...

A long-held theory involving the quickened pace of evolution over short time frames could be explained by an “anomaly” revealed by researchers in a new study. This idea tends to hold that organisms ...

A new study proposes that statistical noise, not biological differences, may explain why evolution seems faster over shorter time frames, challenging long-standing assumptions about evolutionary rates ...

The study blends math, statistics and biology to show that this long-held hyperbolic pattern is an anomaly because it doesn't account for the fact that all species on earth are defined as much by ...

A new book of natural history essays co-written by a University of Kansas paleontologist has been published by Columbia University Press. Bruce Lieberman, Dean’s Professor of Evolutionary Biology and ...
