research Seasonality,.Climatic.Unpredictability,.Food. Deprivation,.and.Polycystic.Ovary.Syndrome
PCOS may have evolved as an advantage in past environments with food scarcity.
research Convergent evolution has led to the loss of claw proteins in snakes and worm lizards
Snakes and worm lizards lost claw proteins due to similar evolutionary changes.
research Size Polymorphisms in the Human Ultrahigh Sulfur Hair Keratin-Associated Protein 4, KAP4, Gene Family
The study found that variations in hair protein genes are likely due to evolutionary deletions or duplications.
research Molecular signaling in feather morphogenesis
Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.
research The Neuroscience of Age Perception
Humans can accurately guess age from faces, with women being slightly better at it, and age perception is linked to evolutionary factors.
research Increased rate of hair keratin gene loss in the cetacean lineage
Cetaceans lost hair genes to adapt to water.
research Comprehensive molecular and cellular studies suggest avian scutate scales are secondarily derived from feathers, and more distant from reptilian scales
Bird scales evolved from feathers, not reptile scales.
research Recurrent functional divergence of early tetrapod keratins in amphibian toe pads and mammalian hair
Early tetrapod keratins evolved into toe pad proteins in amphibians and hair proteins in mammals.
research Is polycystic ovary syndrome a sexual conflict? A review
The conclusion suggests that PCOS may persist due to genetic traits that, while harmful for female fertility, could have provided survival and reproductive benefits to males.
research The Mossman–Pacey Paradox
Men using steroids or finasteride to look more attractive may harm their fertility and sexual function, creating a paradox where they seem fit but may be less able to reproduce.
research The mammary hair of Monodelphis domestica and homology of the mammary pilosebacous unit
Mammary glands evolved from hair organs in Monodelphis domestica.
research EMATOPOIESIS REVOLVES AROUND THE PRIMORDIALEVOLUTIONAL RHYTHM OF INNATE IMMUNITY AND PURINERGIC SIGNALING – A JOURNEY TO THE DEVELOPMENTAL ROOTS
Ancient immune and signaling pathways still regulate blood cell development.
research From Helix to Habitat Understanding Salmon DNA Beyond Biology
Salmon DNA improves skin health and appearance, offering anti-aging and hydration benefits.
research Hair for brain trade-off, a metabolic bypass for encephalization
Human hair loss may have evolved to help increase brain size.
research Ectodermal Organ Stem Cells: Morphogenesis, Population Regenerative Behavior, and Evo-Devo
Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.
research Ancient lineages of the keratin-associated protein (KRTAP) genes and their co- option in the evolution of the hair follicle
Keratin-associated proteins have ancient origins and were used for different purposes before being adapted for hair in mammals.
research Three-dimensional architecture and linearized mapping of vibrissa follicle afferents
Large-scale reconstructions enhance understanding of vibrissal sensory mapping in the brain.
research 3D-printed hair follicles – A new era in hair loss treatments
3D-printed hair follicles could revolutionize hair loss treatments by providing unlimited hair grafts.
research Dermo‐epidermal interactions in reptilian scales: Speculations on the evolution of scales, feathers, and hairs
Reptilian scales, feathers, and hairs evolved from changes in skin cell interactions.
research Tracing the cellular origin of cancer
Understanding where cancer cells come from helps create better prevention and treatment methods.
research Genetic Variation at the MC1R Locus and the Time since Loss of Human Body Hair
Humans lost body hair relatively recently in evolution.
research Sequence-structure based phylogeny of GPCR Class A Rhodopsin receptors
The research found how GPCR Class A Rhodopsin receptors are related and suggested possible substances they interact with.
research Genes for Hair and Avian Keratins
Keratin genes help explain how hair and feathers develop differently in mammals and birds.
research Increased DHT levels in androgenic alopecia have been selected for to protect men from prostate cancer
Higher DHT in male baldness may protect against prostate cancer.
