Bernhard Rensch

Bernhard Rensch was a German evolutionary biologist known for his work on how species develop and change over time. He studied the processes of evolution, especially how different populations of the same species diverge and sometimes become separate species—all within the broader context of biological diversity. Rensch contributed to understanding patterns of evolution and the concept that both size and traits can evolve in predictable ways. His work helps explain the dynamics of development and variation within and between species, providing insights into the complexity of life's evolution.
