Transcript of Gavin de Beer

Interpreted by: Neosha Young Gavin Rylands de Beer My miniature biography An Introduction to Experimental Embryology Combined Mendelian genetics with Charles Darwin’s theory of natural selection. I also built on Walter Garstang’s paedomorphosis, a refutation of the argument that ontogeny recapitulates phylogeny (also called recapitulation), meaning that the embryonic stages of an advanced species’ development are representative of the adult forms of the ancestors of that species Later in Life In 1938 I moved to University College, London, to perform further research in embryology, and in 1940 I became a Fellow of the Royal Society. During World War II I again served in the military, working in intelligence and propaganda. After the war, I returned to London as Professor of Zoology at University College and served as president of the Linnaean Society from 1946 until 1949.

I was born in London, England, on 1 November 1899
I was raised for my first thirteen years in France where my father worked for a telegraph company.
I went to Magdalen College, Oxford, in 1917 but my studies were soon interrupted by World War I.

After serving in the military,I returned to Oxford where I then studied under Edwin Goodrich. I graduated in 1922 but stayed on as a fellow of Merton College and to teach in the Zoology Department. Embryos The shape and location of embryonic internal structures and how they relate and are connected to each other is essential to understanding human development. Medical professionals create a mental picture of this process in order to determine how well the fetus is progressing. More on Embryos The term “embryo” is only used to refer to "eukaryote" or multi-cellular organisms. Typically, people use the term specifically to refer to diploid eukaryotes, which have a complete set of genetic material from two donors.

de Beer Embryos weren't always
determined by computers This genetic material takes the form of haploid sperm and eggs; a haploid cell only contains half a set of chromosomes, meaning that it cannot develop into anything unless it is combined with another one. Most doctors would tell you what
your baby would look like if it was
male or female There were no definite pictures of
embryos until after I explained
what to look for
