Study Notes
Vertebrate Diversity
- Vertebrates are highly successful, with over 70,000 recognized species.
- They inhabit diverse environments including oceans, land, and air.
- Vertebrate diversity is reflected in their varied body plans and adaptations.
Vertebrate Evolution
- Vertebrates have a long evolutionary history.
- Vertebrates are one of two groups to evolve powered flight.
- Powered flight evolved independently three times in vertebrates: in pterosaurs, birds, and bats.
Comparative Biology
- Comparative biology examines biological structures and their functions across species.
- It helps us understand the role of natural selection, adaptation, evolution, and common ancestry in shaping biological diversity.
- Vertebrate wings, despite evolving independently, are derived from the same structure: the forelimbs.
Vertebrate Diversity
- Vertebrates are a diverse group of animals.
- There are approximately 70,000 recognized vertebrate species.
- Vertebrates have adapted to live in oceans, on land, and in the air.
- This diversity reflects their varied body plans and adaptations.
Vertebrate Evolutionary History
- Vertebrates have a long evolutionary history.
- Vertebrates are one of only two groups to evolve powered flight, the other being insects.
- Powered flight evolved independently three times in vertebrates: pterosaurs, birds, and bats.
- Comparative biology involves comparing biological structures and functions across species.
- This helps understand the role of natural selection, adaptation, evolution, and common ancestry in shaping the diversity of biological structures.
- Vertebrate wings evolved independently from the same structure, the forelimbs.
