What genomic feature aids the scaly-foot gastropod in detoxification?
Answer
Gene duplication and loss
Evolutionary biologists have identified specific genetic signatures within the genome of the scaly-foot gastropod that facilitate survival in its toxic environment. A key finding includes the evidence of gene duplication and gene loss associated with detoxification mechanisms. These genomic adaptations allow the organism to effectively process, neutralize, or safely manage the high concentrations of heavy metals that are present in the hydrothermal vent fluids. This sophisticated genetic control is essential for preventing these toxic materials from harming the snail while it simultaneously incorporates some of these metals into its shell.
