Explanation:

Filled in the blanks using key concepts and historical facts from evolutionary biology:

1. The blank describing the variety of life is "biodiversity".
2. The theory about eukaryotic cell origins is the "Endosymbiotic" theory.
3. The collection of facts explaining life diversity is "Evolutionary theory".
4. Modern evolution definition: change in heritable characteristics across "generations".
5. Darwin's work builds on "Charles Darwin's" 19th-century research.
6. Jean-Baptiste Lamarck was the French naturalist; he proposed changes from "use/disuse" or "acquired traits".
7. Alfred Russel Wallace was a "co-developer" of evolution theory.
8. Darwin joined the HMS Beagle, a voyage in the "history" of science, where he made "observations" and collected "specimens" to propose evolution by natural selection.
9. Darwin's 1835 stop was in the "Galápagos Islands".
