One example of macroevolution is the evolution of whales from land-dwelling mammals to fully aquatic marine mammals over millions of years. This process involved significant anatomical adaptations such as changes in limb structure, development of a streamlined body shape, and adaptation of a blowhole for breathing.

What is true of macro-evolution?
It is true that speciation occurs. Since macro-evolution is defined as evolution at and above the species level, this makes the statement that macro-evolution occurs an independently verifiable fact.It is also true that in biology we find nested hierarchies at every level - both at the range of observation from the molecular to the morphological, and at the range of groups from the single species to life-kind in general. This is precisely what we would expect if common descent were true not just within the genus, but for all known life.Furthermore, it is true that we find morphological intermediates in the fossil record: forms that are intermediate morphologically between basal clades in the nested hierarchies of life and clades derived from those basal clades. A basal clade is a group of organisms linked by shared features; a derived clade is a group within that larger group that shares all those features, but is also linked by a distinct set of features present only within that smaller group. An example of this is the basal clade of Apes, and the derived clade of Great Apes, between which exists, for instance the transitional form Pierolapithecus catalaunicus. This, again, is exactly what we would expect to find if macro-evolution were not just true for minor taxa (eg. within a genus), but for all taxa, throughout time.There are many statements about macro-evolution that have been verified through observation. The complete list of possible truths about macro-evolution is too large to detail in a single answer.
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.
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.
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.
Example of macroecolution?
An example of macro-evolution is the appearance of feathers during the evolution of birds from theropod dinosaurs.
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.
Is speciation an example of miro-evolution in organisms?
Yes, speciation is an example of micro-evolution in organisms. It refers to the process by which distinct species evolve from a common ancestor through the accumulation of genetic differences over time. This gradual divergence can lead to the formation of new species that are reproductively isolated from one another.
What do scientists use to study macro evolution?
The fossil record
What do scientist use often to study macro evolution?
The fossil record
When micro evolution occurs over many generations as inherited characteristics lead to changes in populations what has occur?
Macro-evolution. Or, more accurately, speciation.
What is an example of a Macro Control Option?
cheese
What is a example of a macro minerals?
Calcium and Iron
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!
