Fish embryo study indicates that the last common ancestor of vertebrates was a complex animal complete with gills – overturning prior scientific understanding and complementing recent fossil finds. The work places gill evolution concurrent with shift to self-propulsion in our earliest ancestors.
Latest analysis shows that human limbs share a genetic programme with the gills of cartilaginous fishes such as sharks and skates, providing evidence to support a century-old theory on the origin of limbs that had been widely discounted.
The Cambridge Animal Alphabet series celebrates Cambridge's connections with animals through literature, art, science and society. Here, Z is for Zebrafish as we talk to eminent immunologist Professor Lalita Ramakrishnan about her research into new ways of treating tuberculosis.
New research on a highly social fish shows that those reared in larger social groups from the earliest stage of life develop increased social skills and a brain shape, or ‘neuroplasticity’, which lingers into the later life of the fish.
Research reveals that sticklebacks with bolder personalities are not only better leaders but also less sociable than more timid fish. The behaviour of these bolder fish shapes the dynamics of the group.
Latest research shows that coral trout can now join chimpanzees as the only non-human species that can choose the right situation and the right partner to get the best result when collaboratively working.
A major fossil discovery in Canada sheds new light on the development of the earliest vertebrates, including the origin of jaws, the first time this feature has been seen so early in the fossil record
Researchers have uncovered the medieval tipping-point when local fishing could no longer support the demands of the burgeoning metropolis, and catches started to come in from as far away as Arctic Norway.
