摘要	Evolutionary shifts in diel activity patterns shape sensory remodeling across mammals, yet the genetic basis remains poorly understood. Tapirs represent a unique natural experiment, having reverted from a cathemeral ancestor to a nocturnal niche characterized by reduced vision but enhanced hearing and olfaction. Here, we investigate the genetic basis of this phenomenon by generating high-quality chromosome-level genomes for Tapirus terrestris and Tapirus indicus. Comparative analyses revealed extensive lineage-specific remodeling of genes and cis-regulatory elements linked to sensory pathways. Notably, functional validation via CRISPR-Cas9 editing of a tapir-specific conserved noncoding element (CNE74) upstream of the FLT1 gene in mice revealed coordinated sensory effects, including retinal degeneration and reduced visual acuity, yet enhanced auditory sensitivity. These findings suggest that regulatory element evolution may induce pleiotropic effects on competing sensory modalities, offering genetic insights into sensory evolution during temporal niche adaptation and potential relevance to human retinal vascular diseases.
