Not only did microbes diversify within early modern human hosts as they traveled and settled in different geographical locations, they also followed human evolution by limiting themselves to the gut.
Study reveals greater neuron production in the modern human frontal lobe during development compared to the Neanderthal brain. Researchers say this is due to a change in a single amino acid in the TKTL1 protein.
Stool samples taken from Viking latrines allowed researchers to map the genome of the Whipworm parasite. The study maps the parasite's global spread and relationship with human beings.
Axolotls have the ability to regenerate brain areas following an injury. Researchers have mapped cell types and genes associated with neurodegeneration in the axolotl brain, discovering some similarities in the human brain. The findings could pave the way for new neurodegenerative therapies.
Researchers created a molecular atlas of the bearded dragon's brain and compared it to the mouse brain. Findings reveal, contrary to popular belief, mammalian brains consist of an ancient reptilian brain supplemented with new mammalian features. Both reptilian and mammalian brains evolved their own clade-specific neuron types and circuits from a common ancestral set.
A new study sheds light on why humans often use hand movements while talking. Researchers report rhythmic hand gestures affect rib cage movements, leading to a change in lung volume and ultimately aspects of the voice. Infants connect early vocal babbling with hand gestures, demonstrating an early connection between movement and vocal production.
A study of combo jellies reveals the type of messenger that likely functioned in the ancestral nervous system.
Researchers question the widely held belief that modern humans experienced an evolutionary decrease in brain size.
Researchers discovered a new set of chemical reactions that use cyanide, ammonia, and carbon dioxide generates amino acids and nucleic acids, the building blocks of proteins and DNA.
