While the article is lengthy, it is interesting and explores some of the common themes that get rehashed over and over here on CP (eg. Extraordinary claims requiring extraordinary proof, adaptability of science, etc.).
"Everyone suspected dinosaurs were giant birds; then one researcher produced 68 million-year-old protein to prove it. Critics rejected those findings as statistical junk. How a femur sparked a new field of biology—and a scientific smackdown."
