Area of Science:

  • Integrative Biology
  • Evolutionary Biology
  • Developmental Biology

Background:

  • Antlers are unique mammalian appendages with complex annual cycles of growth and shedding.
  • Existing knowledge leaves significant gaps in understanding antler evolution, development, physiology, and pathology.

Purpose of the Study:

  • To identify and discuss critical unsolved problems in antler biology.
  • To propose future research directions for understanding antler evolution, regeneration, and pathology.

Main Methods:

  • The study employs a review and commentary approach, posing interrogatories on key biological questions.
  • It synthesizes existing knowledge and highlights areas requiring further scientific investigation.

Main Results:

  • Identified key questions regarding antler evolution, including self-amputation and regeneration mechanisms.
  • Highlighted developmental enigmas such as precise morphogenesis, velvet transformation, and pedicle regeneration.
  • Addressed physiological puzzles including growth rates, wound healing delays, seasonal synchronization, and calcium acquisition.

Conclusions:

  • Significant gaps remain in our understanding of antler biology, spanning evolutionary, developmental, and physiological processes.
  • Further research is crucial to unravel the complexities of antler cycling, regeneration, and associated pathologies.
