1 EVOLUTION VOCAB Chapter 15 Image from BIOLOGY by Miller and Levine; Prentice Hall Publishing © 2006

2 Change in a population over time; also change in the relative frequency of alleles in a gene pool evolution Differences among individuals within a species Natural variation

3 Structures that develop from the same embryonic tissues, but have different mature forms Homologous structures Organ with little or no function that was functional in an ancestor species Vestigial organ

4 The selection and breeding by humans of animals with certain useful traits from the natural variation in the population Artificial selection Book published by Charles Darwin in which he proposed a mechanism and provided evidence for his Theory of Evolution “On the Origin of Species”

5 Ability of an organism to survive and reproduce in a specific environment fitness Inherited characteristic that increases and organism’s chances for survival adaptation

6 Preserved remains of an ancient organism fossil Islands that Darwin visited on his voyage on the Beagle that started him thinking about how organisms change over time Galapagos

7 Concept that each living species has descended with changes from other species over time Descent with Modifications Idea that organisms that are best suited to their environment will survive and reproduce Survival of the Fittest

8 Trait controlled by a single gene Single gene trait Book published by Charles Darwin in which he proposed a mechanism and provided evidence for his Theory of Evolution “The Origin of Species”

9 The idea that all species, living and extinct, were derived from a common ancestor Common descent Natural selection is also known as ______________ Survival of the fittest

10 Naturalist who gave Darwin incentive to publish his ideas about evolution by writing an essay that described similar ideas. Alfred Wallace French naturalist who hypothesized that organisms acquire traits during their lifetime through use or disuse which can be passed on to offspring Jean-Baptiste Lamarck

11 2 geologists who recognized that Earth is many millions of years old and that processes that changed it still operate today James Hutton & Charles Lyell English economist who reasoned that if the human population kept growing unchecked, there would be insufficient food and space for everyone Thomas Malthus

12 A possible explanation for a set of observations or a possible answer to a scientific problem Another name for natural selection hypothesis Survival of the fittest

13 A well supported, testable explanation of observed natural phenomena THEORY Another name for competition for resources Struggle for existence

14 They proposed that the Earth has changed over millions of years and the processes that caused the change are still happening James Hutton & Charles Lyell NAME THE SCIENTISTS WHO...

15 NAME THE SCIENTIST WHO... Jean-Baptiste Lamarck French naturalist who proposed the idea that characteristics could be acquired or lost by their “use or disuse” during an organism’s lifetime and that these traits could be passed on to offspring. English economist who reasoned that if the human population continued to grow unchecked, sooner or later there would be insufficient food and living space. Thomas Malthus

16 Naturalist who gave Darwin incentive to publish his ideas about evolution by writing an essay that described similar ideas. NAME THE SCIENTIST WHO... Alfred Wallace Proposed the idea that populations change over time as a result of competition for available resources in which individuals with the characteristics best suited to their environment will survive and reproduce Charles Darwin
