Key takeaways

  • J. William Schopf belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect J. William Schopf to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of J. William Schopf from memory before moving on to harder problems.

Reference excerpt

James William Schopf (born September 27, 1941) is an American paleobiologist and professor of earth sciences at the University of California Los Angeles. He is also Director of the Center for the Study of Evolution and the Origin of Life, and a member of the Department of Earth and Space Sciences, the Institute of Geophysics and Planetary Physics, and the Molecular Biology Institute at UCLA. He is most well known for his study of Precambrian prokaryotic life in Australia's Apex chert. Schopf has published extensively in the peer reviewed literature about the origins of life on Earth. He is the first to discover Precambrian microfossils in stromatolitic sediments of Australia (1965), South Africa (1966), Russia (1977), India (1978), and China (1984). He served as NASA's principal investigator of lunar samples during 1969–1974.

Biography James William Schopf was born in Urbana, Illinois, to father James M. Schopf, a paleontologist, and mother Esther Schopf, a school teacher. He was educated at Oberlin College, from where he graduated with AB degree in high honours in 1963. He joined Harvard University in 1963 and earned AM degree in 1965, and PhD in 1968. He was immediately appointed to the faculty of the University of California Los Angeles as Assistant Professor of Paleobiology. He was promoted to Associate Professor in 1970, and to full Professor in 1973. Since 1984 he holds a join post of Director of Center for the Study of Evolution and the Origin of Life at UCLA.

Oldest fossils Schopf is the discoverer of one of the oldest microfossils on Earth. He was the first to discover Precambrian fossils around the world. In 1987, with Bonnie M. Packer, he reported the discovery of microfossils from the Early Archean Apex Basalt and Towers Formation of northwestern Western Australia. He suggested that the apparent cells were cyanobacteria, and therefore oxygen-producing photosynthesis, which lived about 3.3 billion to 3.5 billion years ago. This was the oldest known fossil at the time. However, Martin Brasier and his team from University of Oxford sought to discredit the fossils as "secondary artefacts formed from amorphous graphite" in 2002. Brasier then claimed to have discovered found an older fossil from the same region in 2011.

Personal life Schopf married Julie Morgan in 1966, had a son James Christopher in 1970, and divorced in 1979. He remarried Jane Shen-Miller, a biochemist, on January 16, 1980 and they reside in Los Angeles.

Awards and honours Schopf was honoured with the Sigma Xi Distinguished Lecturer in 1976, Rubey Lecturer in 1976, M.W. Haas Visiting Distinguished Professor of Geology in 1979, Golden Year Distinguished Lecturerin 1980, University of Cincinnati Sigma Xi distinguished lecturer in 1980, extraordinary visiting professor at the University of Nijmegen during 1980–81, Distinguished Lecturer at the Buffalo Museum of Science in 1982; J.A. Bownocker Lecturer at the Ohio State University in 1982, Gold Shield Prize for Academic Excellence in 1993, Frontiers of Knowledge Lecturer in 2000. He is the recipient of the Mary Clark Thompson Medal in 1986, The Paleontological Society Medal in 2012 and the Charles Doolittle Walcott Medal in 2013. He has received two Guggenheim Fellowships (in 1973, for work in Australia; and in 1988, for work in the Netherlands), and Alexander von Humboldt Prize Fellow from Germany. He also received Oparin Medal, Alan T. Waterman Award in 1972, Thompson Medal of the U.S. National Academy of Sciences, and Waterman Medal of the U.S. National Science Board. He was selected by the Botanical Society of America as a Centennial Scientist in 2006. He is elected member of the Institute of Geophysics and Planetary Physics in 1973, Board of Trustees of UCLA Foundation in 1983, Molecular Biology Institute in 1991, of the US National Academy of Sciences in 1998, the American Philosophical Society, the American Academy of Arts and Sciences, the American Academy of Microbiology in 2011, the Linnean Society of London (as Foreign Member), elected President of the International Society for the Study of the Origin of Life, and he is the first-elected Foreign Member of the Scientific Presidium of the A.N. Bach Institute of Biochemistry of the Russian Academy of Sciences. He is life member of the National Center for Science Education.

Worked examples

Example 1 — a first encounter with J. William Schopf

Start with the simplest possible case. Write down what J. William Schopf claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to J. William Schopf before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about J. William Schopf ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of J. William Schopf

In research
J. William Schopf appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses J. William Schopf in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
J. William Schopf is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, American evolutionary biologists, American paleontologists, so understanding it makes those chapters shorter.
In everyday life
Look for J. William Schopf outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
