∙ 12y agoThe facts of macro-evolution as I understand them are as follows:
1. Organisms reproduce with variation.
2. Populations are limited in growth by environmental circumstances.
3. Variants within a limited population compete for resources and reproductive opportunities.
4. This competition results in differing rates of reproduction for different variants.
5. The inherited traits of variants that are more successful in reproducing will spread throughout the population faster than competing traits.
6. For various reasons, including behavioural divergence and geological boundaries, subpopulations can become (partly) reproductively isolated from the main population.
7. This means that variants originating in one subpopulation will not be able to effectively spread their traits throughout the entire population.
8. This means that genetic divergence occurs: the subpopulations become more and more genetically different from their parental stock and from one another.
9. This means that interfertility, the rate of reproduction between subpopulations, declines.
10. At some point, such divergence may effectively result in an cessation interbreeding between subpopulations. At this point speciation has occurred and macro-evolution is fact.

What is a part of macro-evolution?
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
Natural processes such as speciation and gradualism provide the genetic basis for what?
evolution
What principles is not part of Darwin's original theory of evolution by natural selection?
Random processes are not part of the theory of evolution by natural selection.
What is the basic idea of theistic evolution?
Well, theism is the belief in a personal god, and darwinism is darwinian evolution via natural selection, so I imagine theistic Darwinism would be accepting evolution and believing in a personal god at the same time. Christians who accept theistic Darwinism assume that the creation story found in Genesis came about due to macro evolution (i.e. the evolution of one species from another).
What does evolve means?
It means came into being over time by the processes of evolution, as set out by Charles Darwin.
What is a macro evolution?
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
What is a part of macro-evolution?

How do evolution and microevolution differ?
Miroevolution is the change in allele frequency overtime in populations of organisms not leading to speciation; below the taxa level. Macroevolution is speciation. This terminology is not favored by many biologists because there is some implied difference in processes. That is to get from micro to macro. Actually evolution long enough is macro. So, many biologist prefer the terms. Evolution Speciation instead of micro and macro
What is a form of macro evolution?
Macro evolution is just speciation, so you are a form of macro evolution. We and the chimpanzees have a common ancestor that we split from about 6 million years ago. We became Homo sapiensand they became Pan troglodytes.
What are six factors of macroevolution?
I'm not sure that there exists such a thing as "factors of macro-evolution". Macro-evolution is simply what happens when reproductively isolated populations continue to diverge as a result of micro-evolution. They drift apart genetically, behaviourally and morphologically, so that the differences between them become greater and greater. The mechanisms that cause this are reproductive variation and differential reproductive success, the principal mechanisms of evolution.
What are the divisions of evolution?
Evolution is sometimes described as macro-evolution, which is the long-term evolution of an entire new species, and micro-evolution, which is largely to do with less significant evolutionary changes within a species. Many creationists accept the existence of micro-evolution, but say that macro-evolution does not occur.
Is speciation an example of miro-evolution in organisms?
If you use the micro-macro dichotomy then no Speciation is macro evolution. To be precise, biologists, though many biology texts do not conform, say evolution and speciation.
Micro to macro processes in an ecosystem?
t s the difference between micro and macro process in the ecosystem?
What do scientists use to study macro evolution?
The fossil record
Example of macroecolution?
An example of macro-evolution is the appearance of feathers during the evolution of birds from theropod dinosaurs.
What do scientist use often to study macro evolution?
The fossil record
When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
