Macroevolution: the study of changes above the species level, and how they take place.

However, in macroevolution, the traits of the entire species may be important.

Most biologist would not call evolution at the species level "macroevolution".

Its place in evolutionary theory comes under long-term trends or macroevolution.

This explains why 'macroevolution' is perhaps a term biologists do not need to use.

Instead, they say that macroevolution is nothing more than microevolution played out over long periods.

Macroevolution is evolution on a scale of separated gene pools.

Research shows that macroevolution might not be as difficult to achieve as was assumed.

Macroevolution is defined by the scientific community to be evolution that occurs at or above the level of species.

A newcomer to the plant world, York groundsel has been used as an example to support macroevolution.

The issue for biologists is whether there is any sense in having the special term macroevolution.

Some subjects whose study falls within the realm of macroevolution:

Others use terms like macroevolution, or even megaevolution, as if the processes are different from those which occur below species level.

Is there more to macroevolution and the long-term transformation of life than microevolution running for a million generations?

Other teachers focus on molecular evolution, avoiding macroevolution of species, which prevents students from understanding the complete picture.

Underpinning this explanation, I should point out that there is some disagreement on the meaning of "macroevolution".

Her claim that microevolution is quite different from macroevolution is a common contention.

In macroevolution, an accumulation of microevolutionary changes leads to speciation.

Thus, the distinction between micro- and macroevolution is not a fundamental one - the difference is simply the time involved.

Additionally, past macroevolution can be inferred from historical traces.

Some creationists have also adopted the term 'macroevolution' to describe the form of evolution they reject.

The book is divided into accounts of history, genetics, adaptation, evolution and development, and macroevolution.

Although creationists accept microevolution of varieties within a kind, they claim that macroevolution does not happen.

In general, macroevolution is regarded as the outcome of long periods of microevolution.
