Less than a week after The Washington Post first claimed that Jane Goodall’s latest book, Seeds of Hope: Wisdom and Wonder From the World of Plants, contained multiple passages that were lifted from other sources, Grand Central Publishing has postponed the book’s release.

The primatologist, who is most famous for her work with chimpanzees and the creation of the Jane Goodall Institute, wrote Seeds of Hope with freelance writer Gail Hudson. The book was originally scheduled to be released next month, before a total of 12 passages were called into question for plagiarism. Word-for-word copy appeared to be lifted from a website for Choice Organic Teas, as well as others, including several passages that appeared to be lifted from Wikipedia.

In an email to The Washington Post, Goodall issued an apology and stated that, “This was a long and well researched book, and I am distressed to discover that some of the excellent and valuable sources were not properly cited, and want to express my sincere apologies.”

We’re not so sure we would call Wikipedia an “excellent and valuable source,” but perhaps that’s one of the many things Goodall will work on now that the book’s released has been pushed back.
