George Romanes Totally Explained

Everything about George Romanes totally explained

George John Romanes FRS (May 19 1848–May 23 1894) was a Canadian-born English evolutionary biologist and psychologist who laid the foundation of what he called comparative psychology, postulating a similarity of cognitive processes and mechanisms between humans and animals.
   He was the youngest of Charles Darwin's academic friends, and his views on evolution are historically important. He invented the term neo-Darwinism, which is still often used today to indicate an updated form of Darwinism. Romanes' early death was a severe loss to the cause of evolutionary theory in Britain. Within six years Mendel's work was rediscovered, and a whole new agenda opened up for debate.
   Romanes was born in Kingston, Ontario, the third son of George Romanes, a Scottish Presbyterian minister. When he was two years old, his parents returned to England, and he spent the rest of his life in England. Like many English naturalists, he nearly studied divinity, but instead opted to study medicine and physiology at Cambridge University. He graduated from Gonville and Caius College, Cambridge with the degree of BA in 1870, and is commemorated there by a stained glass window in the chapel. It was at Cambridge that he came first to the attention of Charles Darwin; the two remained friends for life.
   Romanes founded a series of free public lectures – still running to the present day – which are named the Romanes Lectures after him. He was a friend of Thomas Henry Huxley, who gave the second Romanes lecture.
   Romanes's support of his claims by anecdotal evidence, rather than empirical tests, prompted C. Lloyd Morgan's warning against Romanes's methods: see Morgan's Canon.

Romanes on evolution

Romanes tackled the subject of evolution frequently. For the most part he supported darwinism and the role of natural selection. However, he perceived three problems with darwinian evolution:

1. The difference between natural species and domesticated varieties in respect of fertility. [thisproblem was pertinent to Darwin, who used the analogy of change in domesticated animals so frequently]
2. Structures which serve to distinguish allied species are often without any utilitarian significance. [taxonomistschoose the most visible and least changeable features to identify a species, but there may be a host of other differences which though not useful to the taxonomist are signifiicant in survival terms]
3. The swamping influence upon an incipient species-split of free intercrossing. [Herewe strike the problem which most perplexed Darwin, with his ideas of blending inheritance. It was solved by the rediscovery of Mendelian genetics, and later work showed that particulate inheritance could underlie continuous variation: see the evolutionary synthesis]

Romanes also made the acute point that Darwin hadn't actually shown how natural selection produced species, despite the title of the famous book! Obviously natural selection could be the 'machine' for producing adaptation, but what exactly was the mechanism for splitting species?
Romanes' own solution to this was called 'physiological selection'. His idea was that variation in reproductive ability caused mainly by the prevention of intercrossing with parental forms was the primary driving force in the production of new species. The majority view then and now was for geographical separation to be the primary force in species splitting (allopatry) and increased sterility of crosses between incipient species as secondary.
