Charles Darwin's On the Origin of Species Celebrates 150 Years

On the Origin of Species, published on 24 November 1859, is a seminal scientific work, considered to be the foundation of evolutionary biology. Darwin's book introduced the theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

Though, Darwin's book did not address directly the question of human evolution, saying only that "Light will be thrown on the origin of man and his history", the possibility of linking humans with earlier apes by descent became clear after 1859 with the publication of On the Origin of Species which argued for the idea of the evolution of new species from earlier ones.

At the time, ideas about the transmutation of species were controversial as they conflicted with scientific mainstream and religious beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to animals. As a result, Darwin's evolution theories were met with ridicule by the scientific community and hostility by the Church before moving to the front line of science.

Marie Curie (1867 – 1934) was Was Born

Marie Skłodowska Curie was a physicist and chemist of Polish upbringing and, subsequently, French citizenship. She was a pioneer in the field of radioactivity, the first person honored with two Nobel Prizes, receiving one in physics and later, one in chemistry. She was the first woman to serve as professor at the University of Paris.

Her achievements include the creation of a theory of radioactivity (a term she coined), techniques for isolating radioactive isotopes, and the discovery of two new elements, polonium and radium. Under her direction, the world's first studies were conducted into the treatment of neoplasms (cancers), using radioactive isotopes.

The Dog Laika Is Launched Into Space - November 3, 1957

The Soviet Union launched Sputnik 2, which carried the dog Laika, the first living creature to be shot into space and orbit the Earth. Sputnik 2 was not designed to be retrievable, and Laika died a few hours after launch, presumably from stress and overheating, probably due to a malfunction in the thermal control system. However, the experiment proved that a living passenger could survive being launched into orbit and endure weightlessness. It paved the way for human spaceflight and provided scientists with some of the first data on how living organisms react to spaceflight environments. On April 11, 2008, Russian officials unveiled a monument to Laika. A small monument in her honor was built near the military research facility in Moscow which prepared Laika's flight to space. It features a dog standing on top of a rocket.
