Lady George Darwin, Beaux's pastel portrait of the former Martha du Puy of Philadelphia, who married Sir George Darwin.

Darwin may have fathered another child, this time with a married woman.

In 1775, Darwin met Elizabeth Pole, daughter of Charles Colyear, 2nd Earl of Portmore, and wife of Colonel Edward Pole ( 1718 – 1780 ); but as she was married, Darwin could only make his feelings known for her through poetry.

When Edward Pole died, Darwin married Elizabeth and moved to her home, Radbourne Hall, four miles ( 6 km ) west of Derby.

* Susannah Wedgwood ( 1765 – 1817 ) ( married Robert Darwin, parents of the English naturalist Charles Darwin )

The elder of these was David Bruce Huxley ( 1915 – 1992 ), whose daughter Angela married George Pember Darwin, son of the physicist Charles Galton Darwin.

He married Florence Henrietta Fisher in 1886 and they had two daughters, Ermengard and Fredegond ; after Maitland's death his widow married Francis Darwin, the son of Charles Darwin.

Charlotte Mildred Massingberd's paternal grandfather Charles Langton ( 1801 – 1886 ) also married Charles Darwin's sister Emily Catherine Darwin after Charlotte Wedgwood's death.

Since its creation the medal has been awarded to 64 individuals, including Francis Darwin, Charles Darwin's son, and two married couples, Jack and Yolande Heslop-Harrison in 1982 and Peter and Rosemary Grant in 2002.

Darwin married Martha ( Maud ) du Puy of Philadelphia.

* Margaret Elizabeth Darwin ( 1890 – 1974 ), married Sir Geoffrey Keynes.

Darwin married Emma Cecilia " Ida " Farrer ( 1854 – 1946 ), daughter of Thomas Farrer, 1st Baron Farrer in January 1880, and they had one son and two daughters:

Darwin was married three times and widowed twice.

First he married Amy Ruck in 1874, but she died in 1876 four days after the birth of their son Bernard Darwin, who was later to become a golf writer.

In September 1883 he married Ellen Crofts and they had a daughter Frances Crofts Darwin ( 1886 – 1960 ), a poet who married the poet Francis Cornford and became known under her married name.

Charles Darwin proposed the theory of universal common descent through an evolutionary process in On the Origin of Species, twice stating the hypothesis that there was only one progenitor for all life forms and ending with " There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one ".

In 1775 he was appointed physician to Birmingham General Hospital ( at the suggestion of Erasmus Darwin, a physician and founder member of the Lunar Society ), but in 1783 he diagnosed himself as having pulmonary tuberculosis and went twice to Portugal hoping the better winter climate would improve his health ; it didn't.

Darwin used the term twice in the 1859 first edition of his work On the Origin of Species, in Chapter IV: Natural Selection, and in Chapter VI: Difficulties on Theory –

The Beagle 2 was named after, which twice carried Charles Darwin during expeditions which would later lead to the theory of natural selection.

Darwin received both this and another warning at least twice by radio, no later than 9: 37 a. m.

The Ghan, run by Great Southern Railway between Adelaide and Darwin arrives twice weekly in each direction and can pick up and set down passengers on request.

Darwin regularly attended clinical wards in the hospital despite his great distress about some of the cases, but could only bear to attend surgical operations twice, rushing away before they were completed due to his distress at the brutality of surgery before anaesthetics.

Darwin was young and generally in good health, though six months previously he had been ill for a month near Valparaiso, but in 1837, almost a year after he returned to England, he began to suffer intermittently from a strange group of symptoms, becoming incapacitated for much of the rest of his life.

Lyell and Hooker were instrumental in arranging the peaceful co-publication of the theory of natural selection by Darwin and Alfred Russel Wallace in 1858: each had arrived at the theory independently.

Quite strong remarks: no doubt Darwin resented Lyell's repeated suggestion that he owed a lot to Lamarck, whom he ( Darwin ) had always specifically rejected.

John Clements Wickham named the region " Port Darwin " in honour of their former shipmate Charles Darwin, who had sailed with them on the ship's previous voyage which had ended in October 1836.

The ship's captain, Commander John Clements Wickham, named the port after Charles Darwin, the British naturalist who had sailed with them both on the earlier second expedition of the Beagle.

It was the same fleet that had bombed Pearl Harbor, though a considerably larger number of bombs were dropped on Darwin than on Pearl Harbor.

Many of the proponents of Darwinism at that time, including Huxley, had reservations about the significance of natural selection, and Darwin himself gave credence to what was later called Lamarckism.

Butler developed the three chapters of Erewhon that make up " The Book of the Machines " from a number of articles that he had contributed to The Press, which had just begun publication in Christchurch, New Zealand, beginning with " Darwin among the Machines " ( 1863 ).

For example, at the time that Darwin first published On the Origin of Species by Means of Natural Selection ( 1859 ), no remains of human ancestors had yet been found.

Darwin did not use the term in Origin of Species until its sixth edition in 1872, ( though earlier editions did use the word " evolved ") by which time Herbert Spencer had given it scientific currency with a broad definition of progression in complexity in 1862.

Faunal succession was one of the chief pieces of evidence cited by Darwin that biological evolution had occurred.

His grandfather, an amateur naturalist by the name of Walter Drawbridge Crick ( 1857 – 1903 ), wrote a survey of local foraminifera ( single-celled protists with shells ), corresponded with Charles Darwin, and had two gastropods ( snails or slugs ) named after him.

Other theories included the pangenesis of Charles Darwin ( which had both acquired and inherited aspects ) and Francis Galton's reformulation of pangenesis as both particulate and inherited.

However, the quote in context shows that Darwin actually had a very good understanding of the evolution of the eye.

Lyell's books had widespread influence, not least on the up and coming young geologist Charles Darwin who read them with enthusiasm during his voyage on the Beagle, and has been described as Lyell's first disciple.

Studies of Charles Darwin's notebooks have shown that Darwin arrived separately at the idea of natural selection which he set out in his 1859 book On the Origin of Species, but it has been speculated that he may have had some half-forgotten memory from his time as a student in Edinburgh of ideas of selection in nature as set out by Hutton, and by William Charles Wells and Patrick Matthew who had both been associated with the city before publishing their ideas on the topic early in the 19th century.

In 1999, his Australian tour was cut short when he had to be hospitalized in Darwin with viral meningitis.

Darwin was a physician and poet who had studied at Cambridge and Edinburgh ; Boulton had left school at fourteen and started work in his father's business making metal goods in Birmingham at the age of 21.

When 14 surviving B-17 Flying Fortresses and 143 personnel of the heavy bombardment force were withdrawn from Mindanao to Darwin, Australia in the third week of December 1941, Headquarters FEAF followed it within days.

While evidence of increasing frequency of melanic forms in the Lepidoptera was available during Darwin ’ s lifetime – the first observations were made in 1848 – current understanding is that it was not until 1896, 14 years after Darwin ’ s death, that Tutt explicitly linked melanism with natural selection.

Richard Darwin Keynes, CBE, FRS ( ; 14 August 1919 – 12 June 2010 ) was a British physiologist.

On 14 May 1856 Darwin began what became his draft for a book titled Natural Selection.

* Darwin spared Ingrid's fury ( Aust BC News, 14 March 2005.

After the 14 surviving bombers of the B-17 force escaped to Darwin, Australia just ten days into the war, and with only a handful of fighters remaining, FEAF was broken up as an organization on December 24 and moved by individual units into the peninsula.

The two rheas were also distinct species, and on 14 March Gould's announcement of this finding to the Zoological Society of London was accompanied by Darwin, who presented a paper on how distribution of the two species of rheas changed going southwards.

Some 14 years after Brown ’ s initial edition, the grandfather of Charles Darwin, Dr. Erasmus Darwin, in the introduction to the American edition of 1816 of his Zoonomia, placed Brown in the context of the stream of medicine from the time of the Greeks.
