Summary

Story summary

Recent research examined the evolutionary rates of novel gene emergence in terrestrial and aquatic species using the NCBI RefSeq database.
Scientists found weak hits for novel core housekeeping genes (HGs), indicating low sequence identity.
They performed Gene Ontology (GO) enrichment analysis to identify significant biological functions in terrestrial events, comparing them to a bilaterian background.
Statistical methods, including Fisher’s Exact Test and Principal Component Analysis (PCA), assessed differences between semi-terrestrial and fully terrestrial groups.
The study used MCMCTree for molecular clock analysis, estimating divergence times with high reliability and suggesting distinct evolutionary patterns between habitats.
