Observation: Animals found on islands look similar to animals found on neighbouring islands and the closest continent. How does this observation support the theory of evolution by natural selection?

Name 3 of the 6 different categories of evidence used to document Evolution and what are the (2) categories of evidence for Morphology?

What causes variation among a population of living things and  How can variation in one generation influence the next generation? Is the  variation in a population will be examined as the “raw material” upon which natural selection acts.  Why are there so many different kinds of living things? Comparing species that exist today reveals a lot about their relationships to one another and provides evidence of common origins. This session explores the theory of evolution: change in species over time.

. What is adaptive radiation? Explain it with the example of Darwin's finches.

What is true about evolution by natural selection? a. It is a largely random process. b. Homology shows that convergence is a useful tool for deducing adaptive function. c. Mothers are invariably members of the same species as their offspring, so selection can never create new species. d. Harmful recessive genes are eliminated more rapidly than harmful dominant genes. e. None of the above is true.

Thinking about Natural Selection and Adaption, what if instead the predators were 4 different spoons: ¼ teaspoon, 1 teaspoon, 1 tablespoon, and 1 large serving spoon? Then what if each time beans (the prey) were captured, they had to be immediately emptied into a narrow-necked jar (with an opening about the size of 1 teaspoon)? What do you think the outcome of the experiment might be in this new situation? (Which “predator” will be the most successful, which the next most, etc. down to the least successful, and why?) Be sure to explain your reasoning

How is Aristotle’s “scale of nature” idea linked to early evolutionary thought? In what ways does it differ from modern scientific evolutionary theory?

How would you apply this in a Lamarckian explanation? Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten. Please use your knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths. Please use your Knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths.

Topic: Galapagos Finches Darwin’s readings took him to a predictive theory of how species might change with time: what later thinkers have called microevolution. Darwin’s philosophical worldview then took him beyond his evidence to a conviction that environmental constraints could create whole new structures and organisms. Soon Darwin’s theory of macroevolution replaced the Creator with an environment that could create solely by constraint. For your thread: According to Chapter 13 section 13.1, define microevolution and macroevolution. The Galapagos islands have a great diversity of landscapes – from lush vegetation to nearly barren lava fields yet the Galapagos Finches survive on each island. How can this be explained? Using the varying bills of the Galapagos Finches in figure 13.3 and additional research, explain how microevolution is evidenced.
