Holocentric chromosomes, in contrast to the commonly known monocentric ones, exhibit a remarkable tolerance for fragmentation. They have independently evolved multiple times in both plants and animals. Despite their rarity, holocentrics might have significantly influenced the colonization of land half a billion years ago, while also gaining relevance as significant agricultural pests in contemporary times. Furthermore, these chromosomes are increasingly becoming focal points in studying chromosomal speciation and comprehending the impact of recombination on species success within dynamic or stable environments.
