As a consequence of its key role in male sex determination, the Y chromosome has unique genetic properties that lead to it carrying highly informative haplotypes that evolve largely through the simple accumulation of mutations. Advances in technology have allowed ~10 Mb of Y-chromosome DNA to be...
The human X chromosome has a unique biology that was shaped by its evolution as the sex chromosome shared by males and females. We have determined 99.3% of the euchromatic sequence of the X chromosome. Our analysis illustrates the autosomal origin of the
then “the only economic value of brains left would be the creative thinking of which they are capable” (Guilford,1950). While Guildford’s position is certainly provocative, he may have overestimated the extent to which the
Machine learning bias, also known as 'algorithm bias' or 'AI bias,' is a phenomenon that occurs when an algorithm produces results that are systemically prejudiced due to erroneous assumptions in the machine learning (ML) process. Continue Reading By Stephen J. Bigelow, Senior Technology Editor...
Empathy is the ability to imagine what it must be like in someone else's situation. It is an essential part of what it means to be human, to the extent that we are suspicious of anyone who does not show empathy in their behavior. 46 We read novels, watch televi...
There is a great deal of evidence that both human and chimpanzee infants communicative nonverbally, with gestures and sounds. There are a few studies that have shown cultural variation in the types of gestures used by human infants (e.g., Abels,2020; Kwon et al.,2018), and in the freque...

Birds are among the best-studied animal groups, but their prehistoric diversity is poorly known due to low fossilization potential. Hence, while many human-driven bird extinctions (i.e., extinctions caused directly by human activities such as hunting, as
With the progress of artificial intelligence and the emergence of global online communities, humans and machines are increasingly participating in mixed collectives in which they can help or hinder each other. Human societies have had thousands of years
