![]() I also found variations in different species depending on their living conditions and the environments they inhabited. I carefully recorded that, depending on the food source, the finches had different features in order to survive.ĪLFRED WALLACE: Likewise, whilst I was in Brazil in 1848, in the Amazon, collecting specimens of butterflies, insects and birds, I observed the different species and recorded my findings accurately. For example, I observed adaptations of finches' bodies, beaks, and claws on the Galapagos Islands. ![]() While I was there I started to put into practice my scientific method, this was through-ĪLFRED WALLACE: -experimentation in the form of observation.ĬHARLES DARWIN: Yes, observation and documentation was key to this discovery. imitates monkeyĬHARLES DARWIN: To prove this hypothesis was correct I set off on my voyage on the HMS Beagle to Australia and the Galapagos Islands. We have evolved over time from simple specimens that first lived over three billion years ago.ĬHARLES DARWIN: So, how did we come up with our theory on evolution and natural selection?ĪLFRED WALLACE: Well, for some time now myself and Charles Darwin have both been independently and unknowingly investigating the connection between animals and humans, asking the scientific question what the origin of plants and animal species is, where we came from, and how we all came to be.ĬHARLES DARWIN: Yes, and would you believe, humans shared a common ancestor with chimpanzees millions of years ago. Always trying to take all the credit for our joint theory of evolution aren't you?ĬHARLES DARWIN: Keep your hair on, Wallace, I was just trying to make a start.ĪLFRED WALLACE: Natural selection is the survival of the fittest. The better they adapt, the more likely they are to survive and reproduce passing on those good genes and characteristics to their offspring.ĪLFRED WALLACE: Excuse me Charles, unbelievable, you seem to have started without me. Natural selection is the adaptation of organisms to their environment and the conditions in which they live. ![]() My theory is plants and animals do not stay the same, they change over time. CHARLES DARWIN: Hi fans, followers and friends, Charles Darwin here, the man who's going to give you the theory of evolution and natural selection.
