The voyages of discovery had revealed the existence of chimpanzees, orangutans, and gibbons the gorilla remained unknown to European science until the s, and the bonobo, until the sand anatomical comparisons soon suggested these animals were somehow connected with human beings. As the Comte de Buffon put it, an ape "is only an animal, but a very singular animal, which a man cannot view without returning to himself" Histoire naturelle, vol. The fact that humans and apes share many anatomical traits did not escape Linnaeuswho is often cited as the first classifier to assign the two to a single taxonomic order. In the first edition of the Systema Naturaehe placed both in Order Anthropomorpha, which he later renamed as Order Primates 10th ed.

A comparison of charles darwin and jean baptiste lamarcks theories

Context This lesson provides an opportunity for students to compare the theories of two historically important evolutionary scientists: Jean Baptiste Lamarck and Charles Darwin. In this lesson, students explore the basic principles behind Darwin's mechanism of natural selection.

They then extend their understanding of Lamarck's and Darwin's models by using them to explain phenomena and by comparing them to one another.

Furthermore, this lesson presents a helpful way of concluding an examination of Lamarck's ideas and preparing for a more in-depth study of Darwin's model of natural selection.

In previous lessons, students should have examined Lamarck's hypothesis. In this activity, students are introduced to the principles of natural selection using an online animated movie. Students then present their own ideas about evolution by proposing explanations of observed characteristics of animals, such as the speed of cheetahs or the behavior of naked mole rats.

They are then asked to distinguish between a Lamarkian explanation and a Darwinian explanation for the development of long legs in wading bird species such as herons and egrets. Finally, students work in pairs to develop their own scenarios using Lamarck's and Darwin's models to explain the origin of island bird species.

The goal of these exercises is for students to critically examine two models that explain the observed biological evolution and diversity of life on earth.

Through repeated encounters with Lamarkian and Darwinian explanations, students will have the opportunity to determine why the Darwinian model is more plausible and therefore accepted by the scientific community today. Research shows that students have a tendency to think in Lamarckian terms.

That is, students often invoke the needs of organisms when accounting for change over time Bishop and Anderson, The apparent confusion may be reflected in statements such as "leopards evolved their spots in order to survive better in their environment," or "elephants evolved their large ears so that they could disperse their body heat better.

Discussion of Lamarck's ideas will provide a context in which a clear distinction can be made between these ideas and those of Darwin. In this lesson, students are asked to explain phenomena using both Lamarckian and Darwinian theories.

In doing so, students will come to see that the Lamarkian explanation is unsatisfactory while the Darwinian mechanism of natural selection is plausible and consistent with our current knowledge of genetics. BrainPOP is subscription site. However, it is possible to view a movie by taking a free trial.

It is important to inform students of this viewing issue and to encourage them to use the controls pause, rewind, fast-forward so that they can complete all the assigned questions.

Motivation Tell students that they will look at Darwin's model of natural selection a little more closely and then compare his model to that of Lamarck's. Ask students these questions. As students discuss and answer these questions, note student responses on chart paper or the board and save.

These questions are designed to pre-assess student understanding and misconceptions about the theory of natural selection. After students have completed the motivation assignment, review the questions again and note student responses next to their original statements.

This will allow students an opportunity to reflect on their own ideas and learning. What is natural selection? Is it a fact or a theory? What is the difference between natural selection and evolution?

The main problem faced by evolutionary biologists was the issue of the origin of species. How did Lamarck explain how new species emerge? How did Darwin explain how new species emerge? Do you think there was any similarity in the models proposed by the two scientists?

What are the main differences between the two models? Refer students to the Comparing Theories student E-Sheet. Review the directions and technical issues with the class. If students are unfamiliar with the BrainPOP movies and viewing controls, pull up a different movie from the science index on a class computer connected to a classroom monitor.

Show students how to use the four viewing control buttons to skip back a section or to pause, rewind, and fast-forward the film. Assign the activity for homework. In class, after students have completed their assignment, discuss the questions.Jean-Baptiste Lamarck, in his Zoological Philosophy, described the transmutation of species, proposing that a species could change over time, in , Charles Darwin and Alfred Russel Wallace provided a compelling account of evolution and the formation of new species.
