Great question, Daniel!
Cells can change a lot during a process called ‘differentiation’, but it is not like evolution that Charles Darwin described many years ago.
Before you’re born your cells are constantly changing during the developmental stage. Each type of cell has a setting that decides what it does in the body. And over time all of the cells you need, with their individual settings (like neurons, fat cells, muscles, bone etc.) are made. However, there is no ‘evolution’ going on here, but they do change a lot!
Some would argue that cells do ‘evolve’ and others would argue that they do not. But there’s one thing that is for sure and that is that cells can change over time to act and look differently!
