Paleontologists have made an astonishing discovery, unveiling the earliest known evidence of pheomelanin, the pigment responsible for red hair, in the fossil record.
The groundbreaking revelation came from studying 10 million-year-old frog fossils, marking a significant milestone in paleobiology.
Unearthing Ancient Colors
A recent study published in Nature Communications on Oct. 6 detailed the findings.
Paleontologists uncovered preserved fragments of pheomelanin in ancient amphibians, a pigment also known to produce ginger-colored hair in animals and humans.
The extinct frog species, known as Pelophylax pueyoi, lived during the Early Miocene and inhabited regions of what is today Spain.
Pushing the Boundaries of Fossil Study
This breakthrough discovery was part of a meticulous study where researchers, aiming to understand the fossilization process better, examined liver tissues from the frog remains.
The liver is rich in pheomelanin.
Their comprehensive study examined black, ginger, and white bird feathers, contributing to a broader understanding of pigment degradation during fossilization.
Despite the adversities fossils face, such as heat and pressure, the study elucidated that “traces of biomolecules can survive being cooked during the fossilization process,” according to Maria McNamara, a study co-author.
Navigating the Mysteries of Pheomelanin
The scientists are navigating the uncharted territories of pigment evolution, particularly focusing on understanding how and why pheomelanin evolved.
This pigment, intriguingly, has shown toxicity, posing risks to animals by causing damage to certain cells when interacting with sunlight.
Such findings open avenues to explore the survival and evolutionary mechanisms of these ancient species despite the toxicity of the pigment.
A Gateway to Understanding Ancient Animal Colors
The discovery paves the way for broader explorations into the world of pigments in the fossil record, opening doors to reconstruct and understand the vivid world of ancient animals.
“This is the first molecular record of pheomelanin in the fossil record,” said Tiffany Slater, the lead author of the study, emphasizing the importance of looking for pigments in older fossils to unravel the mysteries of evolution and the enigmatic existence of ginger pigments despite their inherent toxicity.
Looking Forward: A Journey into the Past
This revolutionary discovery holds promise for future research, fostering hope for more profound insights into the evolution of different pigments, their survival strategies, and their manifestation in the appearance of ancient creatures.
The passionate quest of these scientists promises to bring us closer to unraveling the vibrant histories that ancient fossils behold, allowing humanity a peek into the mysteries of evolutionary existence.
