Understand the Problem
The image contains a series of biology questions related to evolution, natural selection, genetics, embryology, and homologous structures. The questions are designed to assess understanding of these core concepts in evolutionary biology.
Answer
* Rabbits: B * Mutations: False * Mutation Example: Sickle cell anemia * Fossils: True * Embryos: A * Homologous Structure: B
Here are the answers to the questions:
- Rabbit population in snowy environment: b. Rabbits with white fur would be the adaptive trait in this environment, leading to more white-furred rabbits in future generations.
- Mutations always result in adaptive trait: False
- Example of beneficial/harmful mutation: A mutation causing sickle cell anemia provides resistance to malaria but can cause health problems in individuals without malaria.
- Older fossils in deeper layers: True
- Embryological development evidence: a. Embryos of different species look similar in early stages, suggesting a common ancestor.
- Example of homologous structure: b. The flipper of a dolphin and the wing of a bat.

More Information
These answers are based on the principles of natural selection, genetics, paleontology, and embryology. Adaptive traits increase survival and reproduction, mutations can be beneficial or harmful depending on the environment, fossils in deeper layers are generally older, embryological similarities suggest common ancestry, and homologous structures indicate shared ancestry.
Tips
A common mistake is thinking that organisms can intentionally change their genes to adapt. Another is assuming all mutations are helpful.
