The cracked shell.

“The political realignment is familiar to observers of the Brexit vote and the 2016 American presidential election. The losers, again, will have to accept that persuasion is made more difficult by insisting that anyone who disagrees with them is stupid or immoral.”

Egg laying is a pretty fundamental thing that life does. Immediately before fertilised eggs came unfertilised eggs in asexual reproduction. Before that came:
Heterothallic mating occurs when two amoebae of different mating types are present in a dark and wet environment, where they can fuse during aggregation to form a giant zygote cell. The giant cell then releases cAMP to attract other cells, then engulfs the other cells cannibalistically in the aggregate. The consumed cells serve to encase the whole aggregate in a thick, cellulose wall to protect it. This is known as a macrocyst. Inside the macrocyst, the giant cell divides first through meiosis, then through mitosis to produce many haploid amoebae that will be released to feed as normal amoebae would.
Since this is wordy the tl:dr is basically that two amoebas join together to become a giant cannibal. They use the bodies of the slain as a protective cover so the goop within can start subdividing into new life.

So basically the critters became fertilised eggs within themselves. Later, instead of giving their all to reproduction, life evolved to compartmentalise its reproductive cells (into those we know and love).
