How are new species created? An insight into the key evolutionary processes, played out over many generations, which lead to speciation.
- We all originate from a single cell, so why are we so varied?
- Species breed within their group and adapt to their environment.
- Speciation occurs when species are separated and evolve differently and can no longer breed together.
- Speciation is a long process with changes taking place over generations.
Life first began as a simple single cell living in water.
From there, organisms gradually became more complex.
And slowly, over billions of years, diverged into the huge variety of species alive today.
Each node of the tree of life shows lineages splitting to form new species.
But how does this occur?
A species is …
