Different species use the same genes for tooth regeneration.
research Characterization of a 300 Kbp Region of Human DNA Containing the Type II Hair Keratin Gene Domain
The study characterized a 300 kbp region of human DNA containing the type II hair keratin gene domain, identifying six functional type II hair keratin genes (hHb1–hHb6) and four pseudogenes. These genes were organized into two subclusters and expressed in the hair follicle, with pseudogene ψhHbD also transcribed despite mutations. The research suggested an evolutionary divergence of type II hair keratin genes from epithelial keratins and provided insights into their genomic organization and expression, contributing to the understanding of hair formation and structure. Additionally, the study highlighted the role of transcription factors in regulating these genes and suggested a higher gene density in this region than previously assumed.
research Convergent Evolution of Cysteine-Rich Keratins in Hard Skin Appendages of Terrestrial Vertebrates
Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.

5 / 109 resultscommunity He turned 71 last week. It looks like his hairline proceeded as he aged. Do you think he's on fin or dut? Or maybe some ancient esoteric chinese remedy?
The conversation humorously speculates on whether an elderly man's good hairline is due to finasteride, dutasteride, or genetics. It also discusses the role of DHT and genetics in hair loss.
community Why do we get bald from evolutionary perspective
Baldness is not an evolutionary disadvantage because it occurs after reproductive age. Treatments like Minoxidil and Finasteride are used for androgenetic alopecia but don't address the root cause.
community Does girlfriend ASMR overpower finasteride?
A humorous discussion on hair loss, suggesting girlfriend ASMR might counteract finasteride's effects, with a proposed experiment involving finasteride, ASMR, and control groups. Participants joke about evolutionary theories, ASMR, and the effects of DHT on balding.
community Hair loss and ethnicity - Caucasian men the most likely to experience hair loss
The conversation discusses how Caucasian men are more likely to experience hair loss due to genetic predisposition, with factors like the androgen receptor on the X chromosome playing a significant role. The user also expresses confusion about the evolutionary reasons for hair loss, especially in colder climates where it would seem beneficial to retain hair for warmth.
community If ancient hunter gatherer women had just selected for men with hair we wouldn't be in this mess
Hair loss is humorously blamed on ancient selection preferences, with discussions on genetics and societal norms. Treatments like finasteride are mentioned as modern solutions.
