What was Darwin’s evidence for natural selection?
Anatomical Evidence
These physical changes were necessary for the survival of the finches. Darwin noticed the birds that did not have the right adaptations often died before they were able to reproduce. This led him to the idea of natural selection. Darwin also had access to the fossil record.
What is Darwin’s theory of evolution How was it proven?
On the Origin of Species by Means of Natural Selection, was first published in 1859 after Darwin returned home from a five-year voyage of discovery. In the seminal book, Darwin argued that organisms gradually evolved through a process called ‘natural selection’ — often known as survival of the fittest.
What evidence supports Darwin’s theory of evolution?
Fossil evidence supports evolution.
You have read that Darwin collected many specimens of fossils on his trip. These specimens provided evidence that species existing in the past were very similar to species living during Darwin’s time.
