Explore a comprehensive lecture on the microbiome's role in evolution, presented by Alejandro Frank from the Centro de Ciencias de la Complejidad at Universidad Nacional Autónoma de Mexico. Delve into the complex interactions between hosts and their microbiota, examining how these relationships influence adaptability and fitness of holobionts. Discover an evolutionary model that demonstrates the importance of specialized microbial diversity in host adaptation and the emergence of complex organisms. Investigate concepts such as dysbiosis, symbiotic interactions, and coevolution within ecosystems. Learn about real-world examples including the effects of antibiotics, microgravity, and historical events on host-microbiome relationships. Gain insights into metagenomic studies, mutations, and the critical network theory that underlies this fascinating area of research.
