This marks the era of the Bikonts, the lineage that produced all modern plants and algae. These cells moved like tiny rowboats, using two flagella at the front of the cell to “pull” themselves through the water. Imagine a cell being towed by two microscopic proto-limbs. When plants later moved to land and became stationary, they largely retired these “pulling” motors, but the legacy remains in the rare swimming sperm of primitive plants like mosses, which still “pull” themselves toward an egg.

Bikonts: Plant Ancestors Split Off Again (Front-Pull Pioneers)
~1.55 Billion Years Ago (+/- 5 million)
Two "Anterior" Flagella – plant rowboats
And now, a premium bonus.
About 1.55 billion years ago, bikonts evolved two flagella to pull themselves forward. These tiny rowboats led to all plants and is not an animal-fungi ancestor.
Subject: Plant Evolution.
By 1.55 billion years ago, bikonts evolved two flagella to pull themselves forward. These tiny rowboats eventually evolved into all plants. Plant cells ability to move was largely lost, but the legacy remains in the swimming sperm of primitive plants like mosses, which still pull themselves toward an egg.
