Scientists say five digits come from a shared evolutionary and genetic blueprint found in fish fins and land limbs.
CRISPR-Cas gene editing helped show that fins and digits share the same development genes, linking fish evolution to human hands.
Most land vertebrates share the same five-fingered bone structure, suggesting a conserved digit plan across tetrapods.
Polydactyly, having extra digits, is linked to overexpression of the sonic hedgehog gene.
Researchers traced fin rays in fish back to a five-digit blueprint encoded by Hox genes.
Exact origins of five digits remain debated, but research emphasizes a shared evolutionary toolkit.
Five-digit evolution likely began millions of years ago as fish fin rays transformed into land limbs.
Five digits are common among land vertebrates, aiding grasp and movement.
Human digits offer an example of how evolution shapes body plans through genetics.
The study links limb development to broader genetic conservation across vertebrates.

Todd Leach chose a prophylactic stomach removal in 2019 after learning his CDH1 mutation raised cancer risk.
The CDH1 mutation significantly increases the risk of stomach and breast cancers for carriers.
Surveillance options included yearly endoscopies, but surgery offered a definitive risk reduction.
Post-surgery, Leach adapted to life without a stomach, eating smaller bites and taking more frequent meals.
The surgery connects the esophagus directly to the small intestine, altering digestion and requiring B12 supplements.
Experts note CDH1-related cancers are rare overall but occur more in certain families.
Leach retired from the Marines after the surgery and adjusted to life post-gastrectomy.
Leach focuses on sharing his experiences to help others facing similar genetic risks.
CDH1 testing can guide decisions between surveillance and surgery for at-risk individuals.
Signet ring cell findings in the stomach indicated early cancer, influencing treatment choice.
