Just like humans and non-human primates, horses have a large number of facial muscles.These allow them to produce a range of facial movements. We also know that facial expressions are an important ...

Gene expression patterns differ substantially among even closely related primate species. The extent of transcriptome divergence between species increases monotonically with evolutionary time ...

Princeton researcher explains link from friendly primate facial gesture to human speech. The throat and facial movements that twist the air pushing through your vocal cords into words could be rooted ...

A number of recent studies have used DNA microarrays to compare patterns of gene expression between closely related species 2,3,4,5,6,7,8,9.Within primates, the focus has been primarily on human ...

Evolutionarily Preserved Signature Found In The Primate Brain Date: June 24, 2008 Source: Uppsala University Summary: Researchers have determined that there are hundreds of biological differences ...

Crying as an emotional expression has been used to describe the vocalizations of many primates, including the coo vocalizations of squirrel monkeys and the whimpers and screams of chimpanzees.

But because Old World primates have both M- and L-pigment genes on each X chromosome, X-inac ti va tion alone does not narrow expression to just one pigment gene per cone cell in those animals ...

Our results also highlight the importance of looking beyond our primate cousins if we are to gain a comprehensive understanding of facial expressions and their evolutionary origins ...

Horses possess a diverse range of 22 distinct facial expressions, comparable in complexity to those of primates. These expressions, identified using the EquiFACS system, are used in various social ...

Horses have a lot of facial muscles, like primates. Serhii Hromov/Shutterstock. We observed groups of domestic horses out at pasture. Whenever they interacted with one another we would hit record ...
