The woolly mammoth project has garnered significant public interest, and Lamm notes that the company has received numerous inquiries about the potential for mammoth meat. He humorously recounts how people are curious about the taste of mammoth, highlighting the fascination with the idea of consuming an animal that has been extinct for thousands of years. Lamm emphasizes that the primary goal of the project is ecological restoration, not culinary exploration, but the curiosity surrounding the mammoth's return reflects a broader cultural interest in de-extinction.

The Tasmanian Tiger and Other Species

In addition to the woolly mammoth, Colossal is also focused on the Tasmanian tiger, or thylacine, which went extinct in the 20th century. Lamm explains that the thylacine was the only carnivorous marsupial in Tasmania and played a crucial role in the ecosystem. The company is working on using genetic material from preserved thylacine specimens to recreate the species. Lamm discusses the challenges of working with such limited genetic data and the importance of understanding the ecological role of the thylacine in its natural habitat.

The conversation also touches on other species that could potentially be brought back from extinction, such as the passenger pigeon and the woolly rhinoceros. Lamm emphasizes that the goal is not just to resurrect these animals for novelty but to restore balance to ecosystems that have been disrupted by human activity. He believes that successful de-extinction efforts could serve as a model for future conservation initiatives, demonstrating the potential for science to reverse some of the damage caused by humanity.

The Ethical Implications of De-Extinction

As the discussion progresses, Rogan and Lamm delve into the ethical implications of de-extinction. Lamm acknowledges that there are valid concerns about playing God and the potential consequences of reintroducing species into environments that have changed significantly since their extinction. He argues that it is essential to approach these projects with caution and to consider the ecological context in which these species will be reintroduced.

Lamm also highlights the importance of involving local communities and stakeholders in the decision-making process. He believes that successful de-extinction efforts require collaboration with indigenous peoples, conservationists, and scientists to ensure that the reintroduction of species aligns with the needs and values of the communities affected. This inclusive approach can help mitigate potential conflicts and foster a sense of shared responsibility for the environment.

The Science of Genetic Engineering

The podcast explores the science behind genetic engineering, particularly the use of CRISPR technology. Lamm explains how CRISPR allows scientists to make precise edits to DNA, enabling them to introduce specific traits into organisms. He discusses the potential applications of this technology beyond de-extinction, including improving crop resilience and developing new medical treatments.

Lamm emphasizes that while genetic engineering holds great promise, it also raises ethical questions about the extent to which humans should intervene in natural processes. He advocates for responsible use of the technology, stressing the need for rigorous testing and oversight to ensure that genetic modifications do not have unintended consequences.
