Which of the following was considered a missing link between reptiles and birds?
Correct answer: D. Archaeopteryx
- A. Pteranodon
- B. Avimimus
- C. Caudipteryx
- D. Archaeopteryx
Explanation
The organism considered a missing link between reptiles and birds is Archaeopteryx. It shows features of both groups, making it an important fossil in the study of evolution. Archaeopteryx had feathers, wings, and a wishbone like modern birds but also teeth, claws, and a long bony tail like reptiles. These mixed characteristics suggest that birds evolved from reptilian ancestors. Therefore, Archaeopteryx serves as strong evidence for the evolutionary connection between reptiles and birds.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
