Well there is not much to go off of, but I am very confident the answer would be studying fossil records,
Answer:
Switch from lysogenic to lytic growth.
Explanation:
Lysogenic induction is a term widely used in virology to describe the passage of viruses from the lysogenic cycle to the lytic cycle.
As you may already know, viruses are obligatory parasites and that is why they need to infect a cell in order to reproduce and that is exactly what the lysogenic and lytic cycles are related to.
The lysogenic cycle refers to the situation where the virus cannot reproduce immediately upon entering the cell. For reproduction to occur, it is necessary for the virus to establish a combination between its genetic conditions and the genetic conditions of the cell, while the virus cannot establish this, the cell can follow its cycle in a normal way.
In the lytic cycle, in turn, the virus can reproduce more immediately, because it can quickly assume the functions of the cell that completely loses its control over its cycle. In the lytic cycle, the virus inserts its genetic material into the cell and makes it work to reproduce it.
