One of the first theories of evolution. Organisms can acquire traits over their lifetime.

Stated earth is millions of years old.

Wrote the book "On the Origin of Species"

Who traveled to the Galapagos islands and noted that species on the islands were similar to each other, but had small differences between them?

Who is considered the co-founder of evolution and said that the driving force for evolution was natural selection?

Which naturalist suggested that species evolved by the "use it or lose it" idea?

What idea did Thomas Malthus contribute to Darwin's hypothesis?

Who hypothesized that Earth has, and still is, being constantly changed due to natural forces?

Peter & Rosemary Grant

Uses Birds to study patterns of speciation, biogeography, and the process of adaptation

Uses genomics, phylogenetics, and bioinformatics to better understand how evolutionary processes drive and maintain the diversity we see today (especially in snakes/lizards)

Interested in understanding early embryonic development, the genes that control this development, the evolutionary origins of these genes and how their functions have changed over evolutionary time.
