What is an an example of macroevolution?
Speciation is an example of macroevolution. The slow transition of land tetrapods to whales, the transition of small, many toed creatures into horses. These are not linear so much as branching progressions with the occasional dead end. Darwin's finches are a modern example of macroevolution by adaptive radiation.speciationBirds are reptiles.
What statement about microevolution and macroevolution is true?
Described by the definition for evolution. Evolution is the change in allele frequency over time in a population of organisms.The prefered terms are evolution ( instead of microevolution ) and speciation ( instead of macroevolution ).
What types of evolution are there?
Basically, there's only one type: the shifting in allele frequencies in populations over the generations, driven by reproductive variation, differential reproductive success, and various molecular mechanisms in genetics. There are however numerous distinct phenomena associated with this mechanism, and different patterns to the way it affects populations, depending on circumstances. If one looks at the different 'modes' of speciation, for instance, even though they all follow from the same basic mechanisms, there are allopatric speciation, peripatric speciation, parapatric speciation, and sympatric speciation, each achieving the same thing through the same mechanisms but via slightly different paths.
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 true about microevolution and macroevolution?
Micro evolution can lead to macroevolution

How is sympatric speciation similar allopatric speciation?
They both are mechanisms by which new species arise

How do scientist view the mechanisms of speciation?
there is ongoing study and debate about this processes
What term describe development of new species and mass extinction?
Macroevolution The development of a new species is called speciation.
How is sympatric similar to allopatric speciation?
They both are mechanisms by which new species arise grad point

What are topics of macroevolution are?
Topics of macroevolution include speciation (the process by which new species arise), adaptive radiation (the diversification of a group of organisms into different forms), evolutionary trends (long-term patterns of change in a lineage), and extinction events (massive die-offs affecting a wide range of species).

How did the work of Gregor Mendel contribute to your current understanding of evolution and speciation?
He provided a basic understanding of mechanisms involved in heredity.

microevolution can lead to macroevolution
Large scale evolutionary trends are the result of?
macroevolution .........novanet
