The study suggests that a specific genetic mutation, involving the insertion of an Alu element (a type of transposable DNA sequence), played a critical role in the evolutionary transition from tailed primates to tailless hominoids.

During recombination, the precise breakage of each strand, exchange between the strands, and sealing of the resulting recombined molecules happens. The “chromosomal breakpoints” refers to these places where they break.

Structural variants (SVs) such as deletions, insertions, duplications, inversions and translocations litter genomes and are often associated with gene expression changes and severe phenotypes (ie. genetic diseases in humans).
