Hans Winkler
Hans Karl Albert Winkler (23 April 1877 – 22 November 1945) was a German botanist. He was Professor of Botany at the University of Hamburg, and a director of that university's Institute of Botany. Winkler coined the term 'heteroploidy' in 1916. He is remembered for coining the term 'genome' in 1920, by making a portmanteau of the words gene and chromosome. He wrote: 
This may be translated as: "I propose the expression "Genom" for the haploid chromosome set, which, together with the pertinent protoplasm, specifies the material foundations of the species ..."
Jesús Mosterín
The 21st century has witnessed a vigorous revival of the idea of human nature in the hands of authors like Edward Wilson, Steven Pinker and Jesús Mosterín. The successful sequencing of the human genome and the ongoing research on the function of genes and of regulatory sequences, together with the insights on the workings of the brain, have brought a new actuality and significance to this classical notion. According to Mosterín, the nature of our species "Homo sapiens" is the information genetically transmitted and present in the human genome (in the genetic pool). Your individual nature lies in your own genome, present in the chromosomes of your cells. The human genome has a layered structure and (up to a point) recapitulates the history of our human lineage. The oldest and deepest strata of our nature represent the living functions common to all life on Earth. Subsequent strata reflect later novelties. The newest layers are devoted to the most recent acquisitions, like bipedalism, grip of precision, large brain cortex, language and other abstract or recursive cognitive processes. Mosterín has dealt with the methods and criteria for distinguishing natural from cultural aspects of human capacities and behaviors and has provided a solid basis to theoretical anthropology. He has also engaged in the discussion and clarification of bioethical issues, like research with embryonic stem cells, birth control, abortion and euthanasia, taking always a scientific point of view and a position in favor of human freedom.
