Personal development includes activities that improve
awareness and identity, develop talents and potential, build human capital and
facilitate employ ability, enhance quality of life and contribute to the
realization of dreams and aspirations. The concept is not limited to self-help
but includes formal and informal activities for developing others in roles such
as teacher, guide, counselor, manager, life coach or mentor. When personal
development takes place in the context of institutions, it refers to the
methods, programs, tools, techniques, and assessment systems that support human
development at the individual level in organizations.

Evolution
Evolution is any change across successive generations in the inherited characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.
Life on Earth originated and then evolved from a universal common ancestor approximately 3.7 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.

Lazuli Bunting
The Lazuli Bunting, Passerina amoena, is a North American songbird named for the gemstone lapis lazuli.
The male is easily recognized by its bright blue head and back (lighter than the closely related Indigo Bunting), its conspicuous white wingbars, and its light rusty breast and white belly. The color pattern may suggest the Eastern and Western Bluebirds, but the smaller size (13–14 cm or 5–5.5 inches long), wingbars, and short and conical bunting bill quickly distinguish it. The female is brown, grayer above and warmer underneath, told from the female Indigo Bunting by two thin and pale wingbars and other plumage details.
