Mary Leakey

Mary Leakey is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mary Leakey rather than just read about it. In short: Mary Douglas Leakey, FBA (née Nicol, 6 February 1913 – 9 December 1996) was a British paleoanthropologist who discovered the first fossilised Proconsul skull, an extinct ape believed to be ancestral to humans. She also discovered the robust Zinjanthropus skull at Olduvai Gorge in Tanzania, eastern Africa.

Key takeaways

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

Reference excerpt

Mary Douglas Leakey, FBA (née Nicol, 6 February 1913 – 9 December 1996) was a British paleoanthropologist who discovered the first fossilised Proconsul skull, an extinct ape believed to be ancestral to humans. She also discovered the robust Zinjanthropus skull at Olduvai Gorge in Tanzania, eastern Africa. For much of her career she worked with her husband, Louis Leakey, at Olduvai Gorge, where they uncovered fossils of ancient hominines and the earliest hominins, as well as the stone tools produced by the latter group. Mary Leakey developed a system for classifying the stone tools found at Olduvai. She discovered the Laetoli footprints, and at the Laetoli site she discovered hominin fossils that were more than 3.75 million years old. During her career, Leakey discovered fifteen new species of animal. She also brought about the naming of a new genus. In 1972, after the death of her husband, Leakey became director of excavations at Olduvai. She maintained the Leakey family tradition of palaeoanthropology by training her son, Richard, in the field.

Biography

Childhood Mary Leakey was born on 6 February 1913, in London, England to Erskine Edward Nicol and Cecilia Marion (Frere) Nicol. The Nicol family moved to numerous locations in the United States, Italy and Egypt where Erskine painted watercolours that he brought back and sold in England. Mary began to develop an enthusiasm for Egyptology during these travels. On her mother's side, Mary was a great-great-great-granddaughter of antiquarian John Frere and shared this same ancestry with historian and archaeologist Sheppard Frere. The Frere family had been active abolitionists in the British colonial empire during the 19th century and established several communities for freed slaves. Three of these communities were still in existence when Leakey published her 1984 autobiography: Freretown, Kenya; Freretown, South Africa; and Freretown, India. The Nicols spent much of their time in southern France where young Mary became fluent in French. In 1925, when Mary was 12, the Nicols stayed at the commune, Les Eyzies, at a time when Élie Peyrony, a French archaeologist and prehistorian, was excavating a cave there. Peyrony was not excavating scientifically during that early stage of archaeology and did not understand the significance of much of what he found. Mary received permission to go through the remnants of his dig. This was where her interests in prehistory and archaeology were sparked. She started a collection of points, scrapers and blades from the dump and developed her first system of classification. The family relocated to Cabrerets, a village of Lot, France. Mary met Abbé Lemozi, the village priest, who befriended her and became her mentor for a time. The two toured Pech Merle cave to view the prehistoric paintings of bison and horses.

Education In the spring of 1926, when Mary was thirteen years old, her father died of cancer and Mary and her mother returned to London. Mary was placed in a local Catholic convent to be educated, and she later boasted of never passing an examination there. Although she spoke fluent French, Mary did not excel at French language studies, apparently because her teacher frowned upon her provincial accent. She was expelled for refusing to recite poetry, and was later expelled from a second convent school for causing an explosion in a chemistry laboratory. After the second expulsion, her mother hired two tutors, who were no more successful than the nuns. After the unsuccessful tutors, her mother hired a governess. Mary's particular interests centered on illustration and archaeology, but formal university admission was impossible with her academic record. Her mother contacted a professor at Oxford University about possible admission, and was encouraged not to apply, as it would be a waste of her time. Mary had no further contact with the university until it awarded her an honorary doctoral degree in 1981. The small family moved to Kensington, in West London, where, though unregistered, Mary attended lectures in archaeology and related subjects at University College and at the London Museum, where she studied under Mortimer Wheeler. Mary applied to work on a number of summer excavations. Wheeler was the first to accept her for a dig. It took place at St Albans at the Roman site of Verulamium. Her next dig was at Hembury, a Neolithic site, under Dorothy Liddell, who trained her for four years until 1934. Her illustrations of tools for Liddell drew the attention of Gertrude Caton Thompson, and, in late 1932, she entered the field as an illustrator for Caton Thompson's book The Desert Fayoum.

Life

Through Caton Thompson, an English archaeologist, Mary met Louis Leakey, who was in need of an illustrator for his book Adam's Ancestors (1934). While she was doing that work they became romantically involved. Leakey was still married and his son Collin had just been born when they moved in with each other. They married after Frida Leakey divorced him in 1936. This ruined his career at Cambridge University. Mary and Louis Leakey had three sons: Jonathan, born in 1940, Richard in 1944, and Philip in 1949. Their fourth child, a daughter, died as a baby. The three boys received much of their early childhood care at various anthropological sites and, whenever possible, the Leakeys excavated and explored as a family. The children accompanied them to various work sites, with dig becoming a family endeavour. The boys grew up with the same love of freedom that their parents had become accustomed to. Mary would not even allow guests to shoo away the pet hyraxes that helped themselves to food and drink at the dinner table. In her autobiography, she rarely mentioned her pregnancies or the difficulties she faced while raising children in Kenya. She smoked a lot, first cigarettes and then cigars, and usually dressed as though completing an excavation. While her husband was alive, they published many joint findings. However, her contributions were often credited to her husband. Louis Leakey died on 1 October 1972 of a heart attack. Mary Leakey continued with the family's archaeological work, becoming a respected figure in paleoanthropology in her own right. Her son, Richard Leakey, also decided to become a paleoanthropologist, and Mary helped him begin his career. Her other two sons, Jonathan and Philip Leakey, pursued other interests.

Worked examples

Example 1 — a first encounter with Mary Leakey

Start with the simplest possible case. Write down what Mary Leakey 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 Mary Leakey 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 Mary Leakey 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 Mary Leakey

In research
Mary Leakey 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 Mary Leakey 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
Mary Leakey is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1996 deaths, 20th-century American anthropologists, so understanding it makes those chapters shorter.
In everyday life
Look for Mary Leakey 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.
