There are fossils of viruses, of sorts, preserved in the DNA of the hosts that they’ve infected. Including you. This molecular fossil trail can help us understand where viruses came from, how they evolved and it can even help us tackle the biggest question of all: Are viruses alive? | Eons • PBS

Viruses have evolved sophisticated mechanisms to infect host cells, hijacking their systems for replication. But what if we told you this process is far more intricate than it seems? Introducing the key stages of viral infection how microscopic invaders turn healthy cells into virus-producing factories. ◦ Attachment: The virus binds to specific receptors on the cell surface,. ◦ Entry: It penetrates the membrane or enters via endocytosis. ◦ Genetic Material Release: The virus injects its DNA or R
