Latif和Lulu探讨了人们对遗传和后天获得性状传递的误解,以及拉马克获得性遗传理论的错误性。他们指出,父母的行为并不能改变孩子的基因。 Chad和Robert讲述了Paul Kammerer的实验及其最终被证伪的故事,以及Kammerer自杀的悲剧。这部分内容展现了科学研究中对立观点的冲突以及科学结论的严谨性。 Chad和Robert介绍了关于老鼠舔舐行为影响幼崽基因表达的研究,这表明环境因素可以影响基因表达,部分支持拉马克主义的观点,但强调这并非基因本身的改变。 Chad和Robert讲述了瑞典Overkalix地区的研究,该研究表明祖父在9-12岁期间的营养状况会影响孙辈的健康状况,这体现了跨代遗传现象。 访谈中还涉及到对Barbara Harris的Project Prevention项目的讨论,该项目通过金钱奖励的方式鼓励吸毒女性采取节育措施,引发了伦理争议。
