Darwin's findings, such as natural selection, provide evidence for microevolution, which involves changes within a species over time. However, they do not offer direct evidence for macroevolution, which involves the formation of new species or higher taxa over long periods. Macroevolution typically requires additional mechanisms, like genetic mutations and genetic drift, to account for larger-scale changes.

What is true about microevolution and macroevolution?
Microevolution refers to small-scale changes in a population's gene pool over a few generations, resulting in adaptations within a species. Macroevolution, on the other hand, involves large-scale evolutionary changes leading to the formation of new species over longer periods of time. Both processes are driven by the same mechanisms of genetic variation and natural selection.
Are there complicated links between microevolution and macroevolution?
Microevolution is small evolutionary changes. Macroevolution is change above the specie level. Biologists debate if this process even exists. Some say they are fundamentally the same thing. It seems that macroevolution is the evolution of evolution. That sounds complicated.
What is the difference between macro evolution and micro evolution?
The difference is one of scale and scope. This is best explained using a single species and its descendants as an example:Every change that happens to the species up to the point of speciation would be classified as "micro-evolution". But after speciation, divergence would not stop: the two new species would continue to diverge from one another, possibly resulting in yet more branching events, more new species. The scope would increase to include all of those as well. At this scale, we're talking about "macro-evolution". When we zoom in on one of those newly emerged species, we can see that the resulting "macro-evolution" is still being generated by the cumulative effects of "micro-evolution" within each individual population.
What is an example of micro-evolution?
An example of micro-evolution is the development of antibiotic resistance in bacteria due to natural selection. When exposed to antibiotics, bacteria with genetic mutations that provide resistance to the drug survive and reproduce, passing on the resistant trait to future generations. Over time, the proportion of resistant bacteria in the population increases, leading to the evolution of antibiotic-resistant strains.
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 level does micro evolution take place?
Where all evolution takes place initially, and some say totally. The population. Microevolution is just this; Evolution is the change in allele frequency over time in a population of organisms. Macroevolution is that change magnified, some say, at the taxa level.

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.
Which of these is an example of macroevolution?
Macroevolution is larger scale evolution above the species level. It happens over a longer period of time than microevolution. For example, microevolution can cause small adaptations within a species, but macroevolution causes more noticeable anatomical changes that give rise to new species and new groups of organisms. There is no real separation between micro- and macroevolution. Microevolution, over time, translates into macroevolution.
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.
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.
Are birds evolved from a dinosaurs an example of micro evolution?
yes

Compare and contrast microevolution and macroevolution?
a microorganism can or can not be harmful for the host body but a pathogen is a microorganism which is always harmful for the host body.so ALL MICROORGANISMS ARE NOT PATHOGEN BUT ALL PATHOGENS ARE MICROORGANISMS.
