What is Preadaptation anthropology?
Preadaptation is: the use of an anatomical feature in a way unrelated to the feature's original function.
Which of the following can Cultural dating be used to date?
Cultural dating can be used to date: ceramics.
How is the process of stratigraphic correlation carried out?
How is the process of stratigraphic correlation carried out? If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, then A is considered older than B.
What is important to creating a fossil record of a species?
Crucial to creating a fossil record of a species is: a good representation in the fossil record. The study of what happens to an organism's remains after death is: taphonomy.
Who was the English scientist who independently Co discovered the theory of natural selection?
The English scientist who independently co-discovered the theory of natural selection was: Charles Lyell.
How did Lamarck contribute to the theory of evolution quizlet?
How did Lamarck contribute to the theory of evolution? He proposed the first serious model of how traits are passed on from parent to offspring, through inheritance of acquired characteristics, though that idea turned out to be incorrect.
What is stratigraphic correlation?
Stratigraphic correlation is the process of establishing which sedimentary strata are the same age at distant geographical areas by means of their stratigraphic relationship.
What is stratigraphy dating in archaeology?
Stratigraphy: Assuming that soil layers in a deposit accumulate on top of one another, and that the bottom layers will be older than the top layers, stratigraphy allows archaeologists to construct a relative chronological sequence from the oldest (bottom) to youngest (top) layers.
Who came up with stratigraphic correlation?
Nicholas Steno The basic principles that underlie stratigraphic correlation were formulated in 1669 when Nicholas Steno (Niels Stensen, 1638–1686), a Danish naturalist, recognized that the succession of strata is directly related to their relative ages.
Who discovered stratigraphy?
priest Nicholas Steno Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment.
How can scientists use the fossil record to find evidence of relationships between different species?
In addition, scientists can roughly date fossils using radiometric dating, a process that measures the radioactive decay of certain elements. Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history.
What was Alfred Russel Wallace known for?
Alfred Russel Wallace was born in Wales in 1823. He has been described variously as a naturalist, a geographer, and a social critic. He even weighed in on the debate as to whether or not life could exist on Mars. However, what he is best known for is his work on the theory of natural selection.
What did Erasmus Darwin discover?
Erasmus Darwin was a respected physician, a well known poet, philosopher, botanist, and naturalist. As a naturalist, he formulated one of the first formal theories on evolution in Zoonomia, or, The Laws of Organic Life (1794-1796).
What did Erasmus Darwin contribute to the theory of evolution?
Darwin expounded one of the earliest theories of evolution (“all vegetables and animals now living were originally derived from the smallest microscopic ones”), and he described the importance of sexual selection to continuing changes within species (“the final cause of this contest among males seems to be, that the …
Who introduced stratigraphy in Indian archaeology?
8. Conserving archaeological resources. Stratigraphy: The concept of stratigraphy in geology had been based on the publication of the book Principles of Geology by Sir Charles Lyell in 1830.

Who is required as the father of stratigraphy *?
The man credited as the "father of stratigraphy," however, was the English engineer and geologist William Smith (1769-1839). In 1815 Smith produced the first modern geologic map, showing rock strata in England and Wales.
Who discovered homologous structures?
In 1859, Charles Darwin explained homologous structures as meaning that the organisms concerned shared a body plan from a common ancestor, and that taxa were branches of a single tree of life.
What does the fossil record tell scientists?
By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments.
What did Darwin and Wallace discover?
Abstract. Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change.
What did Charles Darwin discover?
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.
What did Lamarck discover?
Lamarck is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859): If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring.
Were Erasmus and Charles Darwin related?
Charles Darwin's grandfather, Erasmus Darwin, was one of the leading intellectuals of eighteenth century England, a man with a remarkable array of interests and pursuits. Erasmus Darwin was a respected physician, a well known poet, philosopher, botanist, and naturalist.
Who was the English naturalist who proposed that organisms evolve through natural selection?
naturalist Charles Darwin The theory of natural selection was explored by 19th-century naturalist Charles Darwin.
What theory did Georges Cuvier develop?
In the first half of the 19th century, the French naturalist Georges Cuvier developed his theory of catastrophes. Accordingly, fossils show that animal and plant species are destroyed time and again by deluges and other natural cataclysms, and that new species evolve only after that.
Who introduced stratigraphy?
priest Nicholas Steno Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment.
When was stratigraphy developed?
History of stratigraphy The basic principles of stratigraphy were developed primarily by geologists in the nineteenth century. Many of the fundamental ideas drew on the observations of Jens Jacob Asmussen Worsaae (1821–1885) in Denmark, and Thomas Jefferson in Virginia.
Who introduced the principle of stratigraphy in Indian archaeology?
8. Conserving archaeological resources. Stratigraphy: The concept of stratigraphy in geology had been based on the publication of the book Principles of Geology by Sir Charles Lyell in 1830.
What is the origin of homologous structure?
Although these two structures do not look similar or have the same function, genetically, they come from the same structure of the last common ancestor. Homologous traits of organisms are therefore explained by descent from a common ancestor.
What is the origin of homologous?
It ultimately comes from the Greek homólogos, which means “agreeing.” Homólogos is made from homo-, meaning “same,” and -logos (here meaning “proportional”). Homologous structures are studied in the scientific fields of biology and anatomy.
