Evolution & Adaptation
📋 What it is
Fossils show life changing over time; species adapt to their environments across many generations.
🗣️ Coach says
The fossil record is evolution’s photo album. Over long spans, species change: helpful traits (an adaptation) become more common because those individuals survive and reproduce better. Fossils capture transitions — like early whales with legs — showing how one form gradually became another.
🧠 Memory hook
Evolution = life changing over generations. Adaptations (helpful traits) spread; fossils catch the transitions.
😂 Giggle
Why did the ammonite feel so appreciated?
Because people were always saying it was a-mazing spiral!
😲 Whoa!
Fossils of ancient whales have small back LEGS — proof that whales evolved from four-legged land mammals that returned to the sea.
✅ Quick check: How do fossils of ancient whales with tiny legs support evolution?
Say your answer out loud first — then reveal.
They capture a transition — showing whales descended from legged land animals that adapted to the sea.
Transitional fossils show gradual change between forms.
