Dutch primatologist Frans de Waal was born on October 29th, 1948. He is known for his research demonstrating that moral behavior can be seen in animals, not just humans. De Waal maintained audience engagement through his presentation by using multimedia like video and charts to support his claims. While he was knowledgeable, he lacked excitement and charisma in his delivery compared to other speakers. However, he covered an interesting topic about empathy and reciprocity in animals that still engaged the audience.
