for estimating diversity patterns of species from fossil records, allowing us greater insights into how
early tetrapods responded to the changes in their environment.»
Despite this being a catastrophic event
for plants, it has been unclear how this affected the
early tetrapod community.
Salamanders are particularly good organisms
for studying how locomotion onto land evolved, as their anatomy and ecology is similar to the
earliest tetrapods.
The findings are reported by researchers from Tokyo Institute of Technology (Tokyo Tech), the Centre
for Genomic Regulation (CRG, Barcelona) and their collaborators in the journal eLife and give new insight into how fish evolved to live on land in the form of
early tetrapods.
