A remarkable fossil discovery in the Canadian Arctic has illuminated the evolutionary leap from fins to limbs. Unearthed in 2004, Tiktaalik Roseae, dating back 375 million years, exhibits traits of both fish and early land animals. Its unique anatomy, including weight-bearing fins and a flexible neck, provides crucial insights into how vertebrates began adapting to life on land, a pivotal moment in our planet’s biological history.
