Darwin develops his theories

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.

Emma Darwin : a Victorian life
James D. Loy and Kent M. Loy.
Gainesville, Fla. : University Press of Florida, c2010.
A glimpse into the private home life of the Darwins "A sensitive, intelligent portrait of Emma Darwin and her life at the centre of Victorian science."--Emma Darwin, author ofA Secret Alchemy "Succeeds brilliantly in discovering the poignant story of Emma Darwin and describing the extraordinaryhousehold over which she presided."--Keith Thompson, author ofThe Young Charles Darwin "Emma Darwin emerges in this well-researched and thoughtful biography as a figure of calm strength, whose very nature and story help make possible Charles Darwin's revolutionary work. The Darwin marriage emerges as a remarkable portrait of 'symmetrical and unconditional love.'"--Kay Young, University of California, Santa Barbara In 1808, Josiah Wedgewood II, owner and general manager of the famous pottery and china manufactory that bore his name, welcomed an eighth child into his large, vibrant family. This daughter, Emma, had a relatively happy childhood and grew up intelligent, educated, and religious. A talented sportswoman and an accomplished pianist, she married her cousin Charles Darwin at the age of thirty, bore ten children in their forty-three years together, and patiently nursed her famous husband through mysterious and chronic illnesses. Informed by her strong Christian faith as well as her quick, inquiring mind, Emma learned to coexist with her husband's radical scientific theories, though she worried about the fate of Charles's soul. Although the high spirits of her youth were somewhat dampened by the cares of life, she managed family and household affairs--including the difficult circumstances surrounding the death of three children--with courage, gravity, and a sense of humor. In this charming volume, the wife, companion, and confidante of the father of evolution comes into full focus. Drawing upon Emmarsquo;s personal correspondence as well as the abundant literature about her husband, authors James Loy and Kent Loy reveal the fascinating story of an exceptional woman who remained true to herself despite hardship and who, in the process, humanized her work-obsessed husband and held her family together. 
Revolution in science : how Galileo and Darwin changed our world
Mark L. Brake.
New York : Palgrave Macmillan, 2009.
This is the compelling story of the two biggest events in the evolution of ideas: the revolutions of Galileo and Darwin. The ideological shifts that resulted from their work were crucial not only to science. Their impact on society and culture has been equally decisive up to the current century. Mark Brake captures the adventure and excitement of these two scientists--one who overturned humanity's central place in the universe and another who challenged the very notion of the origins of humankind. Their discoveries in a sense became "weapons of science," that challenged the long-held views of creation and human origins promoted by the Church for centuries. At a time when creationism and intelligent design are again in the news, this is a timely examination of the ways in which faith and science clash, and how the battle for "truth" is a perennial one.

Charles R. Darwin was born on February 12, 1809, a birth date he shares with Abraham Lincoln.  He was a great observer of life; animal, vegetable, and mineral. Darwin was the first of the evolutionary biologists.

Darwin documented his observations, from the finches found in the Ecuadorian Galapagos Islands, to earthworm's effect on soil formation. He also wrote about his geological observations of coral reefs, volcanic islands, and South America.

During his five-year voyage on the ship, The Beagle, Darwin studied animal and plant specimens in geographic areas outside of his home country of England. He documented what he saw by producing manuscripts, letters, and sketches of his observations.

Charles Darwin's On the origin of species : a graphic adaptation
story by Michael Keller ; art by Nicolle Rager Fuller.
New York, NY : Rodale, c2009.
A stunning graphic adaptation of one of the most famous, contested, and important books of all time. Few books have been as controversial or as historically significant as Charles Darwin’s On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Since the moment it was released on November 24, 1859, Darwin’s masterwork has been heralded for changing the course of science and condemned for its implied challenges to religion. In Charles Darwin’s On the Origin of Species, author Michael Keller and illustator Nicolle Rager Fuller introduce a new generation of readers to the original text. Including sections about his pioneering research, the book’s initial public reception, his correspondence with other leading scientists, as well as the most recent breakthroughs in evolutionary theory, this riveting, beautifully rendered adaptation breathes new life into Darwin’s seminal and still polarizing work.
The annotated Origin : a facsimile of the first edition of On the origin of species
Charles Darwin ; annotated by James T. Costa.
Cambridge, Mass. : Belknap Press of Harvard University Press, 2009.
Charles Darwin's On the Origin of Species is the most important and yet least read scientific work in the history of science. Now James T. Costa-experienced field biologist, theorist on the evolution of insect sociality, and passionate advocate for teaching Darwin with Darwin in a society where a significant proportion of adults believe that life on earth has been created in its present form within the last 10,000 years-has given a new voice to this epochal work. By leading readers line by line through the Origin, Costa brings evolution's foundational text to life for a new generation.The Annotated Origin is the edition of Darwin's masterwork used in Costa's course at Western Carolina University and in Harvard's Darwin Summer Course at Oxford. A facsimile of the first edition of 1859 is accompanied by Costa's extensive marginal annotations, drawing on his extensive experience with Darwin's ideas in the field, lab, and classroom. This edition makes available an accessible, useful, and practical resource for anyone reading the Origin for the first time or for those who want to reread it with the insights and perspective that a working biologist can provide.

During Darwin's expedition to the Galapagos Islands he noticed that fiches differ in their structure from one island to another.

Observing nature is one of the oldest scientific methods. With his interest in scientific investigations, Darwin observed the world around him and developed theories that sought to explain what he saw.  He then took the long road of gathering evidence to approve, contradict, or modify his theories and hypotheses.

Over twenty years of research Darwin emphasized the factors controlling population increase, rather than on developing an explanation of species change by mean of a casual theory of life. Darwin published his research as he discovered new ideas. Biologists and other scientists, from Darwin's time until today,  continue to test these ideas as they create hypotheses and theories of their own.
