Which of the following statements concerning selection of species for research is FALSE?

The statement about vertebrate species being favored over invertebrates whenever possible is considered false due to the guideline that species selection for research should primarily align with the goals of the study and the scientific needs rather than a preconceived hierarchy favoring one group over another. In many cases, the use of invertebrates may be more suited to specific research questions and objectives, particularly in areas such as genetics, developmental biology, and ecological studies.

Choosing the appropriate species should focus on the relevance and appropriateness to the research question rather than a rigid preference for vertebrates. Additionally, using invertebrates often comes with fewer ethical and regulatory considerations compared to vertebrates, provided the research does not invoke significant harm or suffering. This flexibility in species selection allows researchers to optimize their experiments, ensuring that the capabilities and characteristics of the species align well with their hypotheses and methodological requirements.

In contrast to the false statement, the options that emphasize species selection based on research goals and the necessity to justify the use of any species for research highlight an important aspect of ethical research practice. These principles ensure that researchers are thoughtful and deliberate in their selection process, considering the well-being of the animals and the scientific validity of their work.
