speciation
yes it s an evidence that a chemical change has been occurred
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
Quantitive evidence is evidence that has to do with numbers. For example. the magnitude of an earthquake the time the earthquake occurred and the length of the earthquake are all types of quantitive evidence
When a change in behaviors has occurred..
The surfaces in contact show signs of degradation.
The two types are Dna, and fossils

A Hybrid sterility is an example of a postzygotic reproductive barrier. This occurs when the offspring of two species are sterile and cannot produce viable offspring of their own. It is a mechanism that prevents gene flow between species after mating has occurred.
Reducing the surface of the beach is a consequence of erosion.

Scientists use a variety of evidence to determine when they think speciation occurred. This includes analyzing fossils, studying genetic similarities and differences between different species, and observing patterns of geographic distribution and reproductive isolation. Additionally, scientists may also use techniques such as radiometric dating to estimate the age of fossils and the timing of speciation events.
