Elisabeth Vrba

Elisabeth Vrba is a scientist who studies how animals and plants change over time. She is a paleontologist, which means she studies fossils. Fossils are the remains of animals and plants that lived long ago. By studying fossils, Vrba can learn about how animals and plants have evolved over millions of years.

Vrba is known for her work on the turnover-pulse hypothesis. This hypothesis says that there are times when many new species appear in a short period of time. These times are called turnover pulses. Vrba believes that turnover pulses are caused by changes in the environment.

Vrba's work has helped us to understand how animals and plants evolve. She has shown us that evolution is not always a slow and steady process. Sometimes, it can happen very quickly.

Elisabeth Vrba was a young woman when she was forced to work in the Auschwitz-Birkenau concentration camp.
