Scientists use phylogenetic trees to illustrate the evolutionary relationships among species. These diagrams depict the branching patterns of evolution, with lines representing ancestral relationships and nodes indicating common ancestors. By analyzing genetic, morphological, or behavioral traits, scientists can infer how closely related different species are. Phylogenetic trees help visualize the history of species divergence over time.

Charles Darwin discovered that selective breeding could lead to significant changes in traits within a species over relatively short periods. His experiments with pigeons demonstrated how specific characteristics, such as size, color, and feather type, could be amplified by choosing which individuals to breed. This observation supported his broader theory of natural selection, illustrating how variation within species could lead to the evolution of new forms over time. Ultimately, it highlighted the role of human intervention in shaping traits, paralleling natural processes in the wild.

The most reliable method to measure an earthquake's strength is the moment magnitude scale (Mw). This scale calculates the total energy released by an earthquake by considering factors such as seismic wave amplitude, the area of the fault that slipped, and the rigidity of the rocks involved. Unlike older scales, such as the Richter scale, the moment magnitude scale provides a more accurate and consistent measure, especially for large earthquakes. It is widely used by seismologists for its comprehensive approach to quantifying seismic events.
