Research conducted at the Department of Biology, University of Padova, has identified critical genomic milestones in the evolution of Homo sapiens, including key chromosomal rearrangements and specific gene variants that contributed to the development of current modern human traits.
Findings challenge traditional models that attribute certain genetic innovations exclusively to modern Homo sapiens. Similarities observed in both modern and archaic human genomes suggest many hallmarks of the Homo sapiens genetic landscape arose before the lineages split.
Homo sapiens evolved through a series of significant genetic events. A population bottleneck approximately 900,000 years ago is thought to coincide with genomic rearrangements, the fusion of chromosome 2 and the translocation of the pseudoautosomal region 2 (PAR2).
