Unit 2 Review - Speciation

The podcast discusses speciation, the process by which new species arise, and its relation to extinction. It explains phylogenetic trees, highlighting the evolutionary history of species. The podcast covers mass extinctions, adaptive radiation, and artificial selection, using examples like dinosaurs and dogs. It delves into mechanisms of speciation, such as allopatric and sympatric speciation, and types of natural selection, including directional and stabilizing selection. The origin of life is explored, with theories like abiogenesis and the Miller-Urey experiment.

Discuss the significance of the last universal common ancestor.

How did the formation of Pangea influence species evolution?

What is sexual selection and how does it affect species diversity?

What evidence supports the theory of abiogenesis?
