Evolution of the population
This line chart example showing evolution of the population from 1801 till nowadays was redesigned from the Wikimedia Commons file: Evolution de la population vertoise 1801 maintenant.JPG.
"Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.
All life on Earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological traits, or by shared DNA sequences. These homologous traits and sequences are more similar among species that share a more recent common ancestor, and can be used to reconstruct evolutionary histories, using both existing species and the fossil record. Existing patterns of biodiversity have been shaped both by speciation and by extinction." [Evolution. Wikipedia]
The line graph example "Evolution of the population" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Line Graphs solution from the Graphs and Charts area of ConceptDraw Solution Park.
