Which individual, related to Charles Darwin, authored the book "Finger Prints"?

The correct answer is Sir Francis Galton, who authored the book "Finger Prints." Galton was not only a relative of Charles Darwin, as a cousin, but also a significant figure in the fields of genetics and biometrics. His work laid the foundation for fingerprint analysis. In "Finger Prints," published in 1892, Galton presented detailed observations and classifications of fingerprints, establishing the uniqueness of each individual's fingerprints and advocating for their use in personal identification.

His insightful contributions helped elevate the significance of fingerprinting in forensic science, influencing later developments in the field. Galton's research was pivotal at a time when the practice of using fingerprints for identification was still relatively new, and his systematic approach provided a scientific basis for methods that are widely employed today.

While other individuals listed made contributions to the field of fingerprint analysis as well, such as Henry Faulds, who is credited with developing methods for obtaining and analyzing fingerprints, or Juan Vucetich, known for creating the first fingerprint identification system in Argentina, Galton's foundational work and influential publication in "Finger Prints" are what most directly connect him to the question regarding authorship.
