Ethics in Biology refers to the moral principles that guide research and practices in biological sciences. This includes considerations around topics such as genetic engineering, animal testing, and biomedical research. Ethical guidelines help ensure that scientific advancements do not harm living organisms or the environment and promote responsible conduct among researchers. Key ethical issues in biology involve the treatment of laboratory animals, the implications of cloning, and the use of stem cells. These concerns require careful deliberation to balance scientific progress with respect for life and the potential consequences of biotechnological innovations on society and ecosystems.
