What do scientists make to show when they think speciation occurred?
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.
When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
Are Fizzing or foaming evidence that a chemical change may have occurred?
yes it s an evidence that a chemical change has been occurred
According to the concept of punctuated equilibrium the sudden appearance of a new species in the fossil record means that?
Speciation occurred instantaneously, I think
What is the evidence that learning is taking place in the classroom?
When a change in behaviors has occurred..
Complete reproduction isolation is evidence that what has occurred?
speciation
Which type of speciation occurred among galapagos islands finches?
allopatric speciation
What type of speciation occurred when a plant population becomes reproductively isolated while living with its parent population?
Sympatric Speciation

What is the change that occurred in peppered moths is an example of what?
Adaptation and speciation through natural selection

Slow change over time in a species is a way to define?
It is called speciation. Speciation can happen through adaptation, which is a change in an organisms genetic code. If adaptation has gone on long enough so that the two organisms can no longer produce offspring, then speciation has occurred.

Did Charles Darwin have evidence to prove evolution?
No, of course not. Evidence does not prove evolution - it validates the theory.Evidence which Darwin had included limited fossils, and observed apparent speciation in birds.
What are 3 events that can lead up to speciation?
Isolation often leads to speciation, because as each isolated population evolves new characteristics, the separate populations eventually get DNA that is too different for the two to breed and have fertile offspring (this is the point when speciation has occurred). In the case that there is not isolation, the whole species must slowly evolve until it becomes a new species. However, here the line between where the speciation actually occurred becomes blurry, because it doesn't happen in a single generation.
What is the difference between divergence and speciation?
Divergent speciation refers to the rise of a new species when organisms that can interbreed and reproduce fertile offspring get separated. Separation can be due to geographical barriers like mountains and lakes.
