The theory of evolution by natural selection was developed in the mid‑1800s by Charles Darwin and Alfred Russel Wallace, with Darwin becoming most closely associated with it through his book On the Origin of Species.

Who “created” the theory of evolution?

If you’re asking who created the theory of evolution , there are two key names:

  • Charles Darwin
    • English naturalist born in 1809.
* Spent years studying plants, animals, and fossils, especially after his famous voyage on the HMS Beagle.

* Described how species change over time through **natural selection** and laid this out in _On the Origin of Species_ (1859).

* Because of this, he’s often called the “father” of evolutionary theory.
  • Alfred Russel Wallace
    • English naturalist born in 1823.
* Independently came up with the idea of evolution by natural selection while working in Southeast Asia.

* In 1858, his paper on natural selection was presented together with Darwin’s writings, prompting Darwin to publish _On the Origin of Species_ soon after.

So, in a quick scoop :

  • Evolutionary ideas existed before, but Darwin and Wallace together formulated the modern scientific theory of evolution by natural selection , and Darwin’s 1859 book made the theory famous and foundational for modern biology.
