FAQ of Transitional fossils.
We've often heard that there are no examples of transitional species in the fossil record. Kathleen Hunt at Talkorigins has put together a FAQ of transitional vertebrate species to answer these claims:
PART I has FISHES TO FIRST MAMMALS & BIRDS:PART 2 has transitions among mammals (starting with primates), including numerous species-to-species transitions, discussion, and references. If you're particularly interested in humans, skip to the primate section of part 2, and also look up the fossil hominid FAQ.
- Introduction:
- Transitions from primitive fish to sharks, skates, rays
- Transitions from primitive fish to bony fish
- Transition from fishes to first amphibians
- Transitions among amphibians
- Transition from amphibians to first reptiles
- Transitions among reptiles
- Transition from reptiles to first mammals (long)
- Transition from reptiles to first birds
