Charles Darwin first thought of the concept of the Tree of Life in the 19th century and his initial sketch of it is still famous today.
Since then, there have been many different interpretations of the tree.
Darwin's sketch separated species into different branches, whereas recent genetic evidence has suggested that genes, and characteristics, can be exchanged between species even after their branches have grown apart.
Here are some drawings of the tree by different scientists, showing how it has evolved in the last 150 years. And you can discover your place in the Tree of Life with our interactive version.
See the Tree of Life that Charles Darwin first sketched in a notebook when he was working on his theory of evolution.
Most of the Earth's biodiversity is made up of single-celled organisms. Here is a modern version of the Tree of Life that focuses mostly on microscopic organisms.
