Deborah Charlesworth FRS FRSE (née Maltby; born 1943) is a population geneticist from the UK, notable for her important discoveries in population genetics and evolutionary biology. [3] [4] Her most notable research is in understanding the evolution of recombination, sex chromosomes and mating system for plants. [3]
She was interested in studying the evolution of maize through chromosomal changes, [58] and being in South America would allow her to work on a larger scale. McClintock explored the chromosomal, morphological, and evolutionary characteristics of various races of maize.
St. Mary's research into the evolution of parental care has caused a shift in the conceptual understanding of the evolution of prenatal care (in fishes). The previous theory proposed by evolutionary biologists is parental care comes at a tradeoff - by engaging in parental care for current offspring, males are decreasing the time and energy ...
It has been suggested the evolution of the human penis towards larger size was the result of female choice rather than sperm competition, which generally favors large testicles. [27] However, penis size may have been subject to natural selection, rather than sexual selection, due to a larger penis' efficiency in displacing the sperm of rival ...

Sexual selection creates colourful differences between sexes in Goldie's bird-of-paradise.Male above; female below. Painting by John Gerrard Keulemans.. Sexual selection is a mechanism of evolution in which members of one biological sex choose mates of the other sex to mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex ...
