Explore Evolution The Arguments for and Against Neo-Darwinism

Further Debate

Further Debate

One way scientists have advanced the frontiers of human knowledge is through spirited, yet civil, debate about the meaning of publicly accessible evidence. Scientists often debate how best to interpret the available evidence. Controversy in science is nothing new. It’s not a distraction; it’s normal. Explore Evolution is part of the continuing debate over Neo-Darwinism. On this page, the authors of Explore Evolution along with other scientists continue the discussion by responding to questions, comments, and critiques related to issues covered by the textbook. Responses are organized in two ways: by major review, and by book section/topic.
