Macroevolution
Description:
Macroevolution refers to the large-scale changes in species over long periods of time, typically involving the formation of new species or the extinction of existing ones. It focuses on the evolutionary processes that occur above the species level, such as speciation, adaptation, and the emergence of new traits and characteristics.
Sample Sentences:
- Scientists study macroevolution to understand how different species have diversified and evolved over millions of years.
- The fossil record provides valuable evidence for macroevolutionary events that have shaped life on Earth.
- Macroevolutionary patterns can be observed by analyzing the genetic relationships between different groups of organisms.
- In the process of macroevolution, small changes accumulate over time and drive the formation of distinct species.
- The study of macroevolutionary trends helps researchers unravel the complex history of life and its interconnectedness.
