Evidence of Common Descent - Evidence From Observed Natural Selection

Evidence From Observed Natural Selection

Examples for the evidence for evolution often stems from direct observation of natural selection in the field and the laboratory. Scientists have observed and documented a multitude of events where natural selection is in action. The most well known examples are antibiotic resistance in the medical field along with better-known laboratory experiments documenting evolution's occurrence. Natural selection is tantamount to common descent in the fact that long-term occurrence and selection pressures can lead to the diversity of life on earth as found today. All adaptations—documented and undocumented changes concerned—are caused by natural selection (and a few other minor processes). The examples below are only a small fraction of the actual experiments and observations.
