这是第一本以书信形式介绍灵长类及其进化的科普书。
人类栖息于地球上，与猿猴同属灵长类。但是我们表现得更像自然界中暴富的乞丐，不仅六亲不认，而且要尽量撇清自己与其他动物的关系。我们把一切污垢都归于兽性，却把所有光环都归于人性。
本书以生动活泼的问答手法，分别对猿猴的进化与分类、身体与健康、美食与生活、性爱与繁殖、行为与文化、社会与交往、智能与心理七个方面给出了系统的科学描述。读者通过了解猿猴，亦增加对自然的归属感。人类、猿猴及其栖息环境是相互依偎的生态系统。维护生态系统的稳定，使我们的责任和立命之本。

This thoroughly and substantially revised second edition explores the full scope and content of secular bioethics. Abortion, infanticide, euthanasia, genetic engineering, informed consent, advance directives, triage decisions, health care reform, and distributive justice are given new and provocative treatments within a systematic reassessment of bioethics as a whole.

These essays by leading scientists and philosophers address conceptual issues that arise in the theory and practice of evolutionary biology. The third edition of this widely used anthology has been substantially revised and updated. Four new sections have been added: on women in the evolutionary process, evolutionary psychology, laws in evolutionary theory, and race as social construction or biological reality. Other sections treat fitness, units of selection, adaptationism, reductionism, essentialism, species, phylogenetic inference, cultural evolution, and evolutionary ethics.
Each of the twelve sections contains two or three essays that develop different views of the subject at hand. For example, the section on evolutionary psychology offers one essay by two founders of the field and another that questions its main tenets. One sign that a discipline is growing is that there are open questions, with multiple answers still in competition; the essays in this volume demonstrate that evolutionary biology and the philosophy of evolutionary biology are living, growing disciplines.
