Mammals that have evolved more developed brains tend to have a smaller size difference between males and females of that species, according to new research. In many mammal species, the males can be ...

A study reveals how seasonal brain shrinking helps some mammals survive winter, offering new insights into brain plasticity ...

Why do cats generally live longer than dogs? New research suggests that longer livespans of mammals like cats could be linked to their bigger brains and more complex immune systems. An international ...

A recent study has upended a long-held assumption in biology: the idea that brain size increases proportionally with body size across all animals. While this relationship has been widely accepted for ...

New research has revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the traditional view of ...

Scientists use digital casts of the interior of mammalian skulls to learn about brain evolution. They find that the relatively large size of mammalian brains was driven by an excellent sense of smell.

An international team of researchers, with the involvement of the UAB, has conducted a study that explains the evolutionary ...

In many mammal species, the males can be bigger than the females (or vice versa), a trait called sexual size dimorphism (SSD). For example, male elephant seals are around three times bigger than ...
