A Biology Letters study discovers hollow melanosomes in the platypus’s hair—previously seen only in birds—challenging the link between melanosome shape and color in mammals. The platypus fur remains dull brown, echidnas lack hollow melanosomes, and researchers are exploring whether this trait relates to the aquatic lifestyle and broader mammalian evolution.
A Biology Letters study reveals platypus hair melanosomes are hollow and spherical—an arrangement previously observed only in birds—challenging assumptions about color in mammals and hinting at an evolutionary link to their aquatic past; echidnas do not share this feature.
New fossils from Cambrian myllokunmingids reveal pineal/parapineal organs with lens-like structures and melanosomes identical to retinal pigment epithelium, implying these ancient vertebrates had four camera-type eyes and supporting deep homology between eyes and the pineal complex.
Scientists have discovered preserved melanosomes in Diplodocus fossils, revealing that the dinosaur likely had a speckled, possibly iridescent appearance, challenging previous depictions of its dull coloration.
