A Lesson on Evolution & Natural Selection
Evolution by means of natural selection is regarded as one of the most significant scientific theories ever elucidated. In his book On the Origin of Species, Charles Darwin (1859) proposed this mechanism to explain how life has changed over geological...
Charles Darwin's Botanical Investigations
[ILLUSTRATION OMITTED] When the work of Charles Darwin is presented in an introductory class, the primary emphases are usually his voyage aboard the H.M.S. Beagle, particularly the time he spent exploring the Galapagos Islands, and the book that...
Darwin's "Imaginary Illustrations": Creatively Teaching Evolutionary Concepts & the Nature of Science
[ILLUSTRATION OMITTED] * Did Darwin Really Say That? When a new theory or hypothesis is put forward in science, we presume that it will be associated with evidence. This is a hallmark of scientific reasoning--theories or hypotheses should be...
Do You Believe in Evolution?
[ILLUSTRATION OMITTED] This is a question that I have been asked mostly by students but even by family This is a question that deserves an answer. This is a question that, when uttered, perpetuates a major misconception about the nature of science,...
Education's Missing Link: How Private School Teachers Approach Evolution
Over 5 million students and 28,000 schools are consistently marginalized or left out of statistics that describe evolution and science education. Although they are relatively few in number compared with their public school counterparts, the millions...
Evolution & Phylogenetic Analysis: Classroom Activities for Investigating Molecular & Morphological Concepts
"Nothing in biology makes sense except in the light of evolution." The title of Theodore Dobzhansky's 1973 essay captures the importance of evolution in today's biology curriculum. Given evolution's central role in modern biology, the absence of abundant...
Experience Millions of Years
Here's a relatively concrete activity to teach the large numbers representing evolutionary deep time. Key Words: Evolutionary time; deep time; teaching large numbers; geological time. [ILLUSTRATION OMITTED] There are many ways to help students...
Florida Teachers' Attitudes about Teaching Evolution
[ILLUSTRATION OMITTED] Before 2008, Florida's science teaching standards did not mention the word "evolution" and only briefly alluded to it as "change over time." This was a large reason why those standards earned an "F" in a national report from...
From the Beginning
There's a tremendous amount of evidence for evolution, but biologists are always looking for more. As with any delving into the past, this isn't easy to do. Time erases evidence. A number of wonderful sites of prehistoric cave art have been found over...
Guest Editorial: Where Is the "Origin" in the Origin of Species?
Even as we celebrated both the bicentennial of the birth of Charles Darwin and the sesquicentennial of the publication of On the Origin of Species, polls in 2009 showed that only 39% of Americans "believe in the theory of evolution" (Gallup, 2009)....
Popgen Fishbowl: A Free Online Simulation Model of Microevolutionary Processes
[ILLUSTRATION OMITTED] Computer models have several features that help in teaching the dynamics of basic concepts in population genetics. Although there is no substitute for a firm understanding of the basic underlying quantitative features of the...
The Power of Natural Selection: A Guided Investigation of Three Case Studies
Compel your students to analyze evolution by involution of these intriguing cases.* *in-vo-lu-tion. 1. a: the act or an instance of enfolding or entangling: involvement. b: complexity, intricacy. 2. exponentiation: the mathematical operation of...
Were Australopithecines Ape-Human Intermediates or Just Apes? a Test of Both Hypotheses Using the "Lucy" Skeleton
[ILLUSTRATION OMITTED] To effectively introduce the evidence for evolution, it is important that a biology teacher have a basic grasp of the anatomy of australopithecines. This is because the presence of evolutionary sequences in the fossil record...
