Rabbit hair fibers are similar to wool and have a hollow center like feathers.
research Evo Devo of the Vertebrates Integument
The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.
research Review: Evolution and diversification of corneous beta‐proteins, the characteristic epidermal proteins of reptiles and birds
Corneous beta-proteins evolved uniquely in reptiles and birds, forming scales, claws, beaks, and feathers.

Integumentary organs adapt and evolve for survival, with potential uses in regenerative medicine.
research Keratin 75 Is a Component of the LINC Complex and Has an Essential Role in Mediating the SOX2 Rapid Healing Response during Wound Repair
Keratin 75 is important for fast wound healing and works with SOX2 and the LINC complex to help skin cells move and repair damage.
research BMP2 and BMP7 play antagonistic roles in feather induction
BMP2 and BMP7 have opposite roles in feather formation.
research Molecular Signaling and Nutritional Regulation in the Context of Poultry Feather Growth and Regeneration
Good feather growth in poultry needs the right balance of proteins, amino acids, minerals, and vitamins.

Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.
research Feather arrays are patterned by interacting signalling and cell density waves
Feather patterns in birds are shaped by signaling interactions and cell movements, with EDA/EDAR crucial for pattern formation.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Morpho‐regulation in diverse chicken feather formation: Integrating branching modules and sex hormone‐dependent morpho‐regulatory modules
Sex hormones, especially estradiol, can change chicken feather shapes and colors.
