Who authored the book "Animal Liberation," which argues against animal experimentation?

The book "Animal Liberation" was authored by Peter Singer, who is a prominent philosopher and bioethicist. In this work, published in 1975, Singer argues for the ethical treatment of animals and critiques practices such as animal experimentation. He presents a strong ethical framework based on utilitarianism, positing that the suffering of animals should be taken into account when making decisions about their treatment.

His arguments have significantly influenced the animal rights movement and have led to increased awareness and discussions about the moral implications of using animals for scientific research. Therefore, recognizing Singer as the author of "Animal Liberation" highlights his vital role in advocating for the rights and well-being of animals through a philosophical lens that challenges conventional views on the subject.

The other figures mentioned, such as Charles Darwin, Claude Bernard, and Rudolf Jaenisch, are associated with different areas of science and philosophy, and while they have contributed to their respective fields, they do not relate directly to the advocacy against animal experimentation in the way Singer does.
