The evolutionary history of insects
Jadranka Rota håller docentföreläsning i biologi.
With about one million described species and several more millions still to be discovered, insects are the most species-rich group of animals on the planet. For hundreds of millions of years, they have dominated all habitats on Earth except open ocean. When did insects arise? Who are they most closely related to? How different are today’s groups from the early lineages that are now extinct? Why are insects so successful? In this lecture, I will attempt to answer these questions with an overview of the insect fossil record as well as what we have learned from timing of divergence analyses of large molecular datasets.
