The Missing Links Problem
Truth Carriers Academy | All AgesEvolution claims all life descended from a common ancestor through gradual changes over millions of years. If true, the fossil record should contain MILLIONS of transitional forms - creatures that are part one thing, part another.
Fossil record: fully formed kinds with gaps between major groups
Darwin admitted the problem of missing ancestors. More fossils worsened the issue.
Cambrian Explosion: sudden appearance of major body plans
1. What does the Cambrian Explosion show about the fossil record?
2. Why did Darwin admit this was a problem for his theory?
Claimed “fishapod” transition form.
Land-animal footprints predate Tiktaalik; it cannot be the ancestor.
Tiktaalik fossil often called the “fishapod”
1. Why can't Tiktaalik be an ancestor of tetrapods?
1. What “dinosaur features” in Archaeopteryx are also found in other birds?
| Category | Examples | Reality |
|---|---|---|
| Apes | Lucy, australopithecines | Extinct apes |
| Humans | Homo erectus, Neanderthals | Human varieties |
| Transitional | --- | None confirmed |
1. What is the typical pattern with “missing link” announcements?
Billions of fossils, ~250k species cataloged; gaps remain.
Invented to explain why gradual transitions don’t exist.
1. What is “Punctuated Equilibrium” and why was it proposed?
| Claimed Transition | Problems |
|---|---|
| Cambrian Explosion | Major body plans appear suddenly |
| Tiktaalik | Footprints older than the fossil |
| Archaeopteryx | Bird features; “bird-like” dinos later |
| Ape to Human | All fossils either apes or humans |
1. Name three problems with claimed “transitional forms”:
