Size doesn’t matter for mammals with more complex brains, according to new study

A recent study published in Nature Communications found that mammals with more developed brains tend to exhibit smaller sexual size dimorphism (SSD), meaning there is less difference in size between males and females. This suggests that complex brain development may be linked to other traits such as social behavior and mate selection.

Evolutionary origin of mysterious immune system molecule in humans revealed

Researchers discovered that the human immune system borrowed a protein from a gene family responsible for cell migration to create an antibody-binding molecule. The J chain, which regulates antibody structure and function, originated from CXCL chemokines, a family of proteins regulating white blood cell movement.

Sea snakes may have evolved to see colors again

Researchers found that the annulated sea snake possesses four intact copies of the opsin gene SWS1, two with ancestral ultraviolet sensitivity and two with evolved sensitivity to longer wavelengths. This suggests that sea snakes have regained color discrimination to distinguish predators, prey, and mates in their marine habitats.
