Topics
Joe Rogan: 本对话探讨了不同犬种的遗传学差异,特别是狼基因和獒犬基因在不同犬种中的比例。Rogan 提出了一个问题,即所有犬种是否都起源于狼,并对不同犬种的体型和性格差异进行了讨论。 Andrew Huberman: Huberman 详细解释了犬种差异的遗传学基础,指出体型和性格差异主要源于狼基因和獒犬基因比例的不同。他提到一个难以在线找到的图表,该图表显示了不同犬种中狼基因和獒犬基因的剂量。他还解释了犬类体型巨大差异的可能原因,即控制IGF-1的基因剂量。此外,他还讨论了不同犬种的嗅觉和视觉能力差异,以及人类在犬种培育过程中对行为和体型的选择。 Andrew Huberman: Huberman 进一步阐述了不同犬种的遗传构成与其嗅觉和视觉能力的关系,并解释了为什么某些犬种的狼基因比例更高。他详细描述了英国斗牛犬的培育过程,以及短鼻子和獒犬基因对该犬种体型和疼痛感受器分布的影响。他还讨论了不同犬种的培育目的,以及人类在培育过程中对疼痛耐受性、忠诚度和攻击性的选择。

Chapters
Discussion about the genetic makeup of dogs, exploring the influence of wolf and mastiff genes on their physical characteristics, temperaments, and behaviors.
  • Dogs exhibit the greatest variation in body size among species.
  • Dog breeds like shepherds retain more wolf genes, influencing their scent and sight sensitivity.
  • Shorter-snouted breeds like bulldogs have less wolf genetic dosing and fewer pain receptors in their faces.
  • Dog breeding has historically focused on selecting desirable traits like herding, guarding, and companionship.
