WebOct 12, 2024 · Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth. WebFeb 2, 2024 · Peaks in speciation rates through time were coincident for Canids (speciation rates estimated from our complete tree) and each of its major subclades (Figures 2A and 3D–F), around 12 to 8 Mya. Therefore, changes in speciation rates were triggered in parallel across different lineages. The peak in our complete tree starts at 12 Mya (λ = 0.25).
