Macroevolution is supported by a combination of evidence from the fossil record, comparative anatomy, embryology, molecular Biology, and biogeography. Transitional fossils show intermediate forms between different groups of organisms, while similarities in anatomical structures across species indicate common ancestry. The accumulation of genetic changes and the observation of speciation events over long periods of time provide further support for macroevolution.

What type of evolution with small scale changes in genes is called?
Some would call that microevolution. I would not. Some divide evolution into micro and macro. Evolutionary biologists prefer to use the terms evolution and speciation.
What statement is true about micro evolution and macro evolution?
Micro evolution refers to small-scale changes in gene frequencies within a population over a short period of time, while macro evolution involves large-scale changes that result in the formation of new species over long periods of time. Both processes involve genetic variation and natural selection, but the difference lies in the scale and time frame of the changes observed.
What is true of macro-evolution?
Macro-evolution refers to the process of evolution at or above the species level, resulting in the formation of new species over long periods of time. It involves significant genetic changes and can lead to the diversification of life forms. Evidence for macro-evolution is seen in the fossil record, comparative anatomy, and molecular biology.
What is the difference between macro evolution and micro evolution?
Microevolution refers to small-scale changes in the gene pool of a population over a short period of time, resulting in variations within a species. Macroevolution, on the other hand, involves large-scale changes over long periods that lead to the formation of new species or higher taxonomic groups through processes like speciation and extinction.
Compare and contrast microevolution and macroevolution?
Microevolution refers to small-scale changes in gene frequencies within a population over generations, leading to adaptations and variations within a species. Macroevolution, on the other hand, involves larger-scale evolutionary changes such as the formation of new species, genera, or higher taxonomic groups over long periods of time. Both processes are part of the overall mechanism of evolution and are interconnected.
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?
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 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 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 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
Why is Christianity banished in school but not evolution?
Because evolution is a proven, testable, scientific theory.
When micro evolution occurs over many generations as inherited characteristics lead to changes in populations what has occur?
Macro-evolution. Or, more accurately, speciation.
Do Pokemon evolve with micro or macro evolution?
i dunno which is which but they evolve with the kind that is just due to a degrading birth defect or mutation for the worse cuz "evolution" is false!
What is the evolutionary significance of the gill slits?
None. Evolution is a myth and can not be proven.
When micro-evolution occurs over many generations as inherited characteristics leads to changes in populations what has occurred?
Macro-evolution. Or, more accurately, speciation.
