Genomic Minimalism

Genomic minimalism refers to organisms that have streamlined their DNA by losing unnecessary genes, resulting in a compact and efficient genome. This process often occurs in species living in stable, specialized environments, where only essential functions are maintained. By shedding excess genetic material, these organisms reduce energy costs associated with DNA replication and maintenance, allowing for faster growth or adaptation. Examples include certain bacteria and parasites, which have evolved minimalistic genomes tailored to their specific lifestyles. Overall, genomic minimalism highlights how evolution can favor simplicity and efficiency by trimming non-essential genetic information.
