Primates have larger brains than most other mammals of their size. This gives them advanced learning and problem-solving abilities. Many primates also live in complex social groups and communicate through vocal sounds,body languageand facial expressions. Humans' closest living relatives are chimpanzees ...
It is highly likely that we have not a single closest relative but, at the genus level, two equally close ones.JonathanMarksSDOSCurrent Opinion in Genetics & DevelopmentMarks J., 1992 Genetic relationships among the apes and humans.Curt Opin Genet Dev. 2(6):883-889....
The Neanderthals were our closest hominin relative and died out thousands of years ago. Like us, they walked on two legs, hunted , made fire and tools, and lived in shelters (caves). They were more advanced than many of us imagine they were thanks to the way they are portrayed in the...

29,30 However, comprehensive whole-brain connectional analyses of chimpanzee-human connectivity divergence, coupled with genetic investigations into species differences in brain connections, are still lacking. Additionally, understanding neuroanatomical and functional asymmetries—linked to advanced cognitive ...
Humans and our closest extant relatives, such as chimpanzees and other great apes, share strikingly similar coding gene repertoires, yet exhibit pronounced phenotypic differences1,2. The major genetic differences between humans and these primates reside in the non-coding regions of the genome3,4. It...
We also show that mice with significantly enhanced devel- opment of SLE due to expression of the alleles Sle1–3 have two mutations in the IgV-like domain of Siglec E, the closest known relative of human SIGLEC12 in the mouse. Targeted mutation of the Siglece gene in mice led to the ...
The loss of the tail is among the most notable anatomical changes to have occurred along the evolutionary lineage leading to humans and to the ‘anthropomorphous apes’1–3, with a proposed role in contributing to human bipedalism4–6. Yet, the genetic m
A genetic region responsible for red blood cell invasion was among a small number of areas found to differ between the genomes of malaria parasites that affect chimpanzees and Plasmodium falciparum, the parasite responsible for the deaths of more than ha
young and old brains in humans, monkeys, and mice. The work shows that gene function in the aging brain slows — dramatically in ones with Alzheimer’s — and that the genes that shut off the most are those that protect the brain against genetic damage from environmental and other factors....
