Synopsis for "No Sign of Life"
A human colleague warns his friends to give up their dangerous time travel experiments lest they alter the entirety of recorded history. He leaves, and the two scientists scoff at his warning since they are unshaken in their belief that the past cannot be changed. They send a camera back to the earliest beginnings of life where it bonks a creature on the head that was just beginning to emerge from a tide pool knocking it back into the water. When they recover the camera in their present and examine its records, they state, "The professor was wrong! Nothing has changed! We knew that the present could never be affected by what happens in the past! And we were right, as usual!" (The last panel shows the two scientists are now reptilian creatures.)
- Mountain of Thunder! is adapted from The Wizard of Lemuria by Lin Carter.
