By 1871 Darwin could no longer hide his views on human evolution and he published The Descent of Man.
It is also the trait for which most empirical evidence suggesting fishing-induced evolution has been analyzed and published (Jørgensen et al. 2007).
Shisan C. Chen (1894 1957) was an excellent geneticist (Fig. 1), who made outstanding contributions to research into the variation, evolution and heredity of goldfish and published many of his findings in scientific and educational journals.
With Time's Arrow and Evolution, published in 1951, Princeton biology professor Harold Blum persuaded many of his peers that any form of life discovered elsewhere in the cosmos would be wildly different from any to be found on Earth.
His research on plant evolution also progressed during this period; he worked on the genetics of forage grasses, looking at polyploidy and the evolution of the Poaceae and publishing numerous papers on the subject though the 1940s.
His latest book, The Tangled Bank: An Introduction to Evolution, was published by Roberts and Company Publishers in 2009.
In "Darwin, His Daughter, and Human Evolution," published in 2002, Randal Keynes, a Darwin descendant who had access to previously private family papers, makes the case, quietly and convincingly, that the view of existence that underlies "The Origin," with its sober stoicism about the role of death and destruction in making new life, was shadowed by Darwin's experience of his child's death.
Darwin frequently acknowledged not only that his fellow naturalist had come up with the same notions independently, but also that realising someone else was on the same trail had spurred him to stop mulling over his own ideas on evolution and get them published.
Death on Earth: Adventures in Evolution and Mortalitywill be published on May 10.
We modelled sloth body size evolution using published mass estimates for extinct and extant taxa using a potentially changing normal distribution for log-transformed sloth body mass data (Additional file 1: Table S1).
