Darwin & His Ideas

Which of the following is NOT part of the 3 types of Biodiversity that Darwin noted

• Species vary locally

• Species vary by color

• Species vary over time

• Species vary globally

Lyell's Principles of of Geology influenced Darwin because it explained how:

• Organisms adapt over time

• Adaptations occur

• The surface of the Earth changes over time

• The Galapagos Islands formed

Who observed variations in the characteristics of plants and animals on different islands of the Galapagos?

• James Hutton

• Charles Lyell

• Charles Darwin

• Jean-Baptiste Lamarck

In addition to observing living organisms Darwin studied the preserved remains of ancient organisms called...?

• fossils

• adaptations

• homologous structures

• vestigial structures

Rheas, ostriches, and emus are all birds which can live in many different places. What pattern of variation did Darwin observe among these large and flightless birds? 

• They all developed the same types of beaks and feather colorings

• Despite living in different parts around the globe, they all settled in very similar ecological habitats

• Darwin didn't discover anything about them. Hutton and Lyell noted a pattern of variation in which they all could fly for very short bursts of time

• Australia once lost a war to the emus

What connection did Darwin make between the Galapagos tortoises and their environments?

• For the most part they all had the same exact traits despite living on islands of varying environments

• They were all completely different due to living on islands of varying environment

• While still similar, they exhibited different traits depending on the environment of the island they were on

Selectively breeding organisms to have traits desired by humans describes which vocab word?

• Acquired Characteristics

• Artificial Selection

• Homologous structures

• Natural Selection

Which of the ideas proposed by Lamarck was later found to be incorrect?

• None of his ideas were wrong; they all still hold up to this day

• Species change over time

• Species descend from other species

• Acquired characteristics can be inherited

• Species are adapted to their environments

Which of the following would an animal breeder use to increase the number of cows that give the most milk?

• Overproduction

• Genetic isolation

• Acquired characteristics

• Artificial selection

According to Malthus, what factors limit population growth?

• Overcrowding

• Too much food

• Herd mentalities

• Undercrowding
