Detailed explanation-1: -Macroevolution refers to evolution above the species level. It focuses on the development of entire groups. An example of one such group is tetrapods, which are animals with four limbs. Evidence of macroevolution is obtained through the study of fossils, geologic data, and modern organisms.

Detailed explanation-2: -Macroevolution refers to evolution of groups larger than an individual. Macroevolution encompasses the grandest trends and transformations in evolution, such as the origin of mammals and the radiation of flowering plants.

Detailed explanation-3: -Macroevolution is evolution over geologic time above the level of the species. One of the main topics in macroevolution is how new species arise. The process by which a new species evolves is called speciation.

Detailed explanation-4: -Macroevolution usually means the evolution of large-scale structures and traits that go significantly beyond the intraspecific variation found in microevolution (including speciation). In other words, macroevolution is the evolution of taxa above the species level (genera, families, orders, etc.).

Detailed explanation-5: -Macroevolution is genetic change that occurs over long time scales, resulting in large changes in heritable traits in a population; changes large enough that we consider this population a unique taxonomic group, or species. Macroevolution is sometimes also termed speciation (the process by which a new species arises).
