Life did not begin with one primordial cell. Instead, there were initially at least three simple types of loosely constructed cellular organizations. They swam in a pool of genes, evolving in a communal way that aided one another in bootstrapping into the three distinct types of cells by sharing their evolutionary inventions. So abiogenesis happened at least three times, and all ‘right’ next to the other?
Also, I notice that this is stated as fact…
