让灭绝物种重获新生 | Beth Shapiro博士
Huberman Lab播客这期嘉宾是进化生物学家、Colossal Biosciences首席科学官Beth Shapiro博士。
她的研究主要聚焦于灭绝物种复活与物种保护。
我们讨论了人类之间的遗传差异，以及科学家如何利用古DNA和现代胚胎学技术，尝试复活猛犸象、渡渡鸟和恐狼，同时帮助保护濒危物种。
我们也探讨了复活灭绝物种涉及的伦理问题，以及合成生物学如何帮助我们构建一个生物多样性更丰富、适应能力更强的世界。
这段视频中，我们讨论了每个人都携带一定比例尼安德特人基因这一话题。很多人会猜测，这对人的活力、智力等意味着什么。但她指出了一个关键：你携带的是哪些尼安德特人基因，与这些基因所占的比例同样重要，甚至更重要。
你怎么看？我们应该让灭绝物种复活吗？那尼安德特人呢？
对于濒危物种，除了传统的繁育和野生栖息地保护，我们是否也应该利用遗传技术来扩大它们的基因库？
也欢迎在下方评论区告诉我，你希望播客讨论哪些话题，或邀请哪些嘉宾。一如既往，感谢你们对科学的关注！
Bringing Extinct Species Back to Life | Dr. Beth Shapiro
My guest is Dr. Beth Shapiro, PhD, is an evolutionary biologist and Chief Science Officer at Colossal Biosciences.
Her work focuses on de-extinction and conservation efforts.
We discuss genetic differences among humans, and how ancient DNA and modern embryology are being used to de-extinct and protect woolly mammoths, dodo birds, and dire wolves, as well as to help conserve endangered species.
We also explore the ethical implications of de-extinction and how synthetic biology can help build a more bio diverse and resilient world.
Here we are discussing the fact that we all have some percentage of Neanderthal genes. A lot of people speculate what that means in terms of vigor, intelligence, etc., but she makes the important point that which neanderthal genes people have is as or more important than the percentage.
What do you think? Should we bring back extinct species? What about Neanderthals?
What about expanding the gene pool of endangered species using genetic tools as opposed to just conventional breeding efforts and wildlands conservation.
Meanwhile, put in any suggestions of topics or guests? You’d like me to cover on the podcast in the comments section below. And as always, thank you for your interest in science!
