Zorluk: OrtaEvidence for Evolution: Paleontology and Fossil Records

Match each paleontological concept or fossil specimen on the left with its corresponding evolutionary significance or application on the right.

  • Archaeopteryx fossilServes as a transitional form displaying both reptilian skeletal traits and avian feathers.
  • Seymouria fossilRepresents an intermediate evolutionary link between early amphibians and true reptiles.
  • Index fossilsEnables relative dating and biostratigraphic correlation of sedimentary rock layers.
  • Radiometric decay analysisDetermines the absolute numerical age of geological strata based on radioisotope decay rates.

Cevap

Archaeopteryx pairs with the reptile-bird transitional form; Seymouria pairs with the amphibian-reptile transition; Index fossils pair with relative dating of sedimentary strata; Radiometric decay analysis pairs with absolute numerical age determination.
The correct pairing aligns each paleontological tool or fossil specimen with its precise evolutionary role: Archaeopteryx links reptiles to birds, Seymouria connects amphibians to reptiles, index fossils facilitate relative rock layer correlation, and radiometric decay yields exact absolute ages.

Adım Adım Çözüm

1
Analyze the transitional fossil organisms and match them with their key lineages.
Archaeopteryx possesses teeth and feathers (reptile to bird transition), while Seymouria displays mixed amphibian and reptilian traits.
Transitional fossils contain structural features shared between an ancestral group and its derived descendants.
2
Distinguish between relative biostratigraphic methods and absolute geological dating techniques.
Index fossils allow relative layer correlation, whereas radio-isotopic decay analysis yields absolute numerical dates.
Relative dating arranges geological events in chronological order, while absolute dating calculates the actual physical elapsed time.
