We are all more closely related than you may think.
Historically, the development of life has been portrayed in distinct stages (Figure 1). Life began at the Root and through time, evolution iron out the kinks to be us, the most complex forms of life on the planet. But this leaves an important question, where did the root come from?
Life is thought to have started from simple inorganic molecules (Figure 2) [1][2]. These particles interacted to make other larger molecules which eventually gained the ability to replicate themselves independently. Imagine, the simplest self replicating unit. For every billion replications an error occurs making a new type of replicant which then over time repeats this process. Add a dash of selection of the best replicants by evolution and a billion years later you get life...
This process is called abiogenesis. If you wait another 3.5 billion years, the process becomes even more complex, and results in multicellular organisms, like us. Whilst the traditional stepped classification (see Figure 1) is useful to scientists, as it makes digestible chunks to interpret, in the real world the process is much more fluid[3]. Similar to the roots of a tree branching out, although many stems are produced it is still the same super organism travelling through time, as shown below.
We are all more closely related than you think, as all life, in short, is us travelling through time!
