Topics
Neil deGrasse Tyson: 对跨代遗传现象表示好奇和认同,并积极参与讨论。 Chuck Nice: 以轻松幽默的方式参与讨论,提出一些大众关心的问题,例如自由意志和环境因素的影响。 Gary O'Reilly: 提出跨代遗传的概念,引发了对祖父母经历如何影响后代基因组的讨论。 Bianca Jones Marlin: 作为神经科学家和表观遗传学家,详细解释了表观遗传学的概念、跨代遗传的机制、以及相关研究成果,并对未来研究方向和伦理问题进行了探讨。她还分享了她在Marlin实验室进行的小鼠实验,以及对荷兰饥饿冬季研究的解读,并讨论了环境因素和创伤性经历对基因表达的影响,以及这些影响如何跨代遗传。她强调了生物体的适应性和生存本能,以及在理解表观遗传机制后,如何更好地应对创伤并改善未来。 Neil deGrasse Tyson: 表达了对跨代遗传的兴趣,并与其他嘉宾一起探讨了该领域的最新研究成果和未来方向。他提出了关于自由意志和人类行为的哲学问题,并对该领域的研究方法和伦理问题进行了思考。 Chuck Nice: 以轻松幽默的方式参与讨论,提出了一些大众关心的问题,例如自由意志和环境因素的影响。他与其他嘉宾一起探讨了表观遗传遗传的机制、以及该领域研究的意义和挑战。 Gary O'Reilly: 提出了跨代遗传的概念,引发了对祖父母经历如何影响后代基因组的讨论。他与其他嘉宾一起探讨了该领域的最新研究成果和未来方向,并对该领域的研究方法和伦理问题进行了思考。

Deep Dive

Chapters
The episode explores the concept of transgenerational epigenetic inheritance, where experiences like stress and trauma can impact future generations' genetic makeup. It delves into how these experiences can alter gene expression and development in offspring, even before conception.
  • Trauma experienced by grandparents can affect future generations.
  • Transgenerational epigenetic inheritance is a real phenomenon.
  • The discussion centers around the impact of stress and trauma on gene expression.

Shownotes Transcript

Was Lamarckian evolution actually right? Neil deGrasse Tyson, Chuck Nice, & Gary O’Reilly learn about the new field of epigenetics and how the lived experiences of past generations can get passed down genetically with neuroscientist & epigeneticist Bianca Jones Marlin.
