This article explores the origins and differences between human and animal faces, emphasizing the face's role in communication and its relevance to plastic surgery, but presents no new research findings.

This review examines the relationship between facial hair trends and the increase in beard transplant surgeries, exploring psychological reasons for the rising demand without presenting new clinical findings.

This manuscript discusses a large-scale cross-sectional analysis on addressing variance in responses to a set of questions by identifying underlying factors, but specific results are not reported in the abstract.

This study indicates that the thermoregulatory hypothesis is most likely the main factor behind the evolution of hairlessness in humans.

PCOS may have evolved as an advantage in past environments with food scarcity.

This article discusses the evolutionary nature of the field of plastic surgery and introduces the new journal, Plastic and Aesthetic Research, without presenting new research findings.

This study identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study observed that developing mammary organs in Monodelphis domestica show mammary hairs in 12-week-old females, which disappear by 18 weeks, with findings suggesting shared characteristics between their nipples and eutherian nipples, supporting the evolutionary link between mammary glands and hair organs.

This article proposes that androgenic alopecia might be an evolutionary mechanism for reducing prostate cancer risk by enhancing UV absorption, rather than being a risk factor.

The document concludes that understanding health requires considering evolutionary perspectives on reproductive fitness, and recognizing the complexity of factors like diet, testosterone, and sexual orientation.

This review discusses the various aspects of insulin resistance and highlights its potential evolutionary benefits, reporting no new experimental findings.

This article suggests that male pattern hair loss might have historically served as an evolutionary signal for women to choose younger male partners, potentially improving population fitness.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

This paper reviews the diagnostic criteria, associated morbidities, and possible evolutionary advantages of polycystic ovary syndrome, but does not report any new findings.

This study identified a new 65 kD and 48 kD keratin pair expressed in specific mouse epithelial sites, suggesting a unique evolutionary branch of hair-related keratins.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that humans have a significantly slower wound-healing rate compared to non-human primates and other animals, suggesting that slow wound healing is a characteristic unique to humans within the primate order and potentially indicating evolutionary adaptations.

This study observed that darker hair is typical in wetter regions for the Indriidae family, while within Propithecus, dark black hair is common in colder forests, suggesting evolutionary adaptations to environmental pressures.

This study identified the NAC transcription factor RD26 as a critical regulator of drought-induced root hair growth restriction in Arabidopsis thaliana, with a similar mechanism observed in tomatoes, indicating evolutionary conservation.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.

This study reports that KRTAP-like proteins, which resemble keratin-associated proteins found in mammals, are also present in the cornified teeth of various lamprey species, suggesting these proteins may serve similar functions in skin appendages across different vertebrates despite independent evolutionary origins.

This study reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.

This study found that redhaired individuals exhibit higher calcidiol levels compared to non-redhaired individuals, suggesting a possible evolutionary adaptation for vitamin D photosynthesis in low UV-B environments in Europe.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

The authors suggest that tooth, dermal scale, epidermal scale, feather, and hair evolved in parallel from a shared placode/dermal cell unit in an early vertebrate gnathostome with odontodes, around 420 million years ago.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study found that the Florida worm lizard has lost certain genes associated with claw development, which are present in other lizard species with claws, suggesting a link between the evolution of their limbless body and the loss of claw-related genes.

This research suggests that hair keratins evolved from claw keratins in a hairless ancestor, with Hoxc13 controlling their expression in tetrapods, evidenced by the knockout of Hoxc13 hindering claw formation in Xenopus tropicalis frogs.

This review examines how genetic variants associated with polycystic ovary syndrome affect reproductive success differently in men and women, supporting the theory that intralocus sexual conflict may explain its persistence.
