New High-Resolution Genome Assemblies Expand Our Understanding of Human-Ape Differences

Ever since researchers sequenced the chimpanzee genome in 2005, they have known that humans share the vast majority of our DNA sequence with chimps, making them our closest living relatives. So what, exactly, sets us apart? While prior ape genome assemblies were helpful in finding single nucleotide changes, many researchers speculate that a variation type that is more difficult to resolve, structural differences in regulatory DNA or in the copy number of gene families, play important roles in species adaptation. Large-scale efforts to sequence and assemble more ape genomes over the last 13 years have expanded our knowledge, but many…
