Darwin's Theory of Natural Selection

The video tutorial covers the concept of evolution, focusing on Charles Darwin's contributions. It begins with an introduction to evolution and Darwin's background, followed by his observations during the HMS Beagle voyage. The tutorial explains Darwin's theory of natural selection, highlighting key points such as variation, survival of the fittest, and descent with modification. It concludes with a discussion of other scientists like Alfred Russell Wallace and Lamar, noting Lamar's incorrect theory about acquired characteristics.

What was Charles Darwin's initial career path before he became interested in natural science?

• Doctor

• Artist

• Engineer

• Lawyer

What was the primary mission of the HMS Beagle during Darwin's journey?

• To find new trade routes

• To study ocean currents

• To map the coast of South America

• To discover new continents

Which location did Darwin visit that significantly influenced his ideas on evolution?

• The Amazon Rainforest

• The Sahara Desert

• The Galapagos Islands

• The Great Barrier Reef

What is the first point of Darwin's theory of natural selection?

• All species are identical

• There is variety in populations

• Species do not change over time

• All organisms are equally fit

According to Darwin, what happens to the offspring that are not fit for survival?

• They evolve into new species

• They migrate to new areas

• They thrive and reproduce

• They struggle and often do not survive

What term did Darwin use to describe the survival of organisms with advantageous traits?

• Artificial selection

• Genetic drift

• Survival of the fittest

• Natural selection

What is the fourth point of Darwin's theory of natural selection?

• Species alive today are descended with modification from ancestral species

• Species evolve through acquired characteristics

• Species are static and unchanging

• All species have a common ancestor

What is the main difference between natural selection and artificial selection?

• Artificial selection is a natural process

• Natural selection is influenced by humans

• Artificial selection occurs in nature

• Natural selection occurs without human influence

Which scientist had a similar idea to Darwin's but is less well-known?

• Gregor Mendel

• Alfred Russell Wallace

• Isaac Newton

• Albert Einstein

What was the main error in Lamarck's theory of evolution?

• He thought acquired characteristics could be inherited

• He believed in natural selection

• He denied the existence of fossils

• He believed all species were created simultaneously
