What does the term 'atavism' refer to in the context of bird behavior evolution?
What does the term 'atavism' refer to in the context of bird behavior evolution?
- A characteristic exclusive to modern bird species
- A trait acquired by birds from their immediate environment
- A behavior unique to birds with long bodies
- A reversion to an ancestral quadruped pattern (correct)
Why is Lorenz's Atavism hypothesis considered inadequate in explaining bird behavior evolution?
Why is Lorenz's Atavism hypothesis considered inadequate in explaining bird behavior evolution?
- It fails to consider the dorsal and ventral scratching routes
- It overlooks the importance of limb locomotion in bird behavior
- It cannot account for the bidirectional pattern changes observed
- It does not address the diversity of species displaying over wing scratching (correct)
What is a distinguishing feature of the development of pattern change in vertebrates according to the text?
What is a distinguishing feature of the development of pattern change in vertebrates according to the text?
- Limbless animals being unaffected by pattern change
- The synchronous flexing of both sides of the body axis
- Tadpoles transitioning directly into limb locomotion
- Axial locomotion relying on the Central Pattern Generator (CPG) (correct)
