This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.

This study found that cold exposure disrupts the circadian rhythm in cultured human cells by reducing oscillation amplitude, which is restored upon rewarming, while human hair follicle cells showed minimal amplitude sensitivity to temperature changes, suggesting an evolutionary advantage related to Hopf bifurcation dynamics.

This study explored the molecular biology of skin adaptations in pangolins, revealing that certain genes for lipid synthesis have inactive patterns, while others related to skin function remain intact, suggesting complex evolutionary changes in their skin physiology.

This study investigated pangolin skin genetics, finding that while sweat gland-related genes are not inactivated, several genes related to sebaceous gland function are, which highlights complex evolutionary adaptations in mammalian skin.

This review discusses the evolutionary history of keratins and reports no new results, highlighting key events that contributed to the development of mammalian hair and integument.

This study examined the evolutionary and functional homology of steroid 5α-reductase and DET2 proteins, identifying protists as a common ancestor, and discovered a new subclass DET2-like in plants, potentially involved in polyprenol reduction.

This review provides an overview of Hox genes, focusing on their evolutionary history, genomic organization, and roles in development, but reports no new study results.

This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

This study proposes that the ability of humans to grow long scalp hair is linked to the evolutionary adjustment of molecular checkpoints that regulate the hair growth cycle, potentially influenced by its roles in communicating age, maturity, and social signals.

This study reviews the genetic mechanisms behind cat coat patterns, revealing that specific loci determine tabby variations and suggesting these patterns could unravel broader developmental and evolutionary biology insights.

This study analyzed RNA-seq data from various animal breeds and suggested that similar molecular mechanisms may underlie wool fineness in different sheep breeds. Researchers identified 32 candidate genes related to hair follicle regulation, providing insights for molecular breeding and evolutionary studies.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This study found that Prdm1 is crucial for whisker development in mice, affecting multiple signaling pathways and possibly playing a role in primates' evolutionary loss of vibrissae.

This article proposes a hypothesis that KRT75, a protein found in hair follicles, was evolutionarily co-opted by ameloblasts during the development of prismatic enamel in synapsids, but reports no new results.

This genetic study identified four new keratin-associated protein genes in sheep, revealing significant sequence variation and suggesting complex evolutionary dynamics, with unique variants in some sheep breeds linking them to Romanov sheep ancestry.

This study provides the first draft of the male Asiatic lion's whole genome, revealing low genomic diversity and highlighting conservation concerns.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

This study suggests that Demodex mites might universally inhabit adult humans, with a phylogenetic analysis indicating potential undiscovered lineages of the D. brevis species based on geographic differences.

This study suggests that human evolution involved accelerated changes in the HR gene, affecting its role in mediating postnatal hair cycling.

This study used genomic analysis to reveal moderate genetic diversity, minimal inbreeding, and specific genes under positive selection in Xiangdong black goats, highlighting their unique adaptation traits and potential for breeding and conservation.

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

This study found that redheaded individuals had higher levels of vitamin D precursor 25(OH)D3 compared to non-redheaded individuals, suggesting a physiological adaptation to low UVB radiation in Europe.

This study found that redhaired individuals consistently had higher calcidiol levels compared to non-redhaired subjects, suggesting a physiological adaptation for vitamin D synthesis in low UV-B conditions.

This review discusses three aspects of cell fate specification across Metazoa and reports no new experimental results, highlighting the formation of nematode equivalence groups, evolution of echinoderm skeletogenic mesoderm, and adult cell fate regulation.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This study highlights the loss of hair-type keratin genes in cetaceans compared to terrestrial mammals, suggesting a potential adaptive role linked to their hairless phenotype and habitat changes.

In this study, researchers found that the female plumage color variations in the common cuckoo are linked to the female-restricted genome and suggest this pattern is maintained by balancing selection, sharing ancestry with the oriental cuckoo.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This study found that the mK6alpha and mK6beta genes in mice are regulated differently at the mRNA level, with implications for understanding K6 gene evolution and function in mammals.
