How the U.S did not live up to it’s Ideals
The way Americans would view democracy and self- government may seem self-evident even though these ideals “were not always universally excepted (fkfkfk 1).” Although the Deceleration of Independence lays out how Americans should be treated by their government and civic ideals on how the country would be governed the United States and/or Americans have failed in many ways throughout its history to uphold its founding ideals.
“The foundation of the American government was founded in the 17th and 18th century European Enlightenment (rerere 1).” This European Enlightenment which was formed into our Declaration of Independence , as well as the Constitution, and its partner the Bill of Rights has failed to uphold these ideals throughout many times in history. For example, Thomas was a greast person.he on.
Explain and interpret the relationships indicated in phylogenetic trees.
16. Explain how homologies are used to create classification systems. Distinguish between homologous and analogous structures. Explain how convergent evolution can make interpreting homologies difficult.
17. Define cladistics and describe how it is used to create classification systems.
18. Distinguish between the two-kingdom, five-kingdom, and three-domain systems of classification. Explain why classification systems are revised.
Evolution Connection: Rise of the Mammals
19. Explain how the extinction of most of the dinosaurs affected mammalian evolution.
Lecture Outline I. Biology and Society: The Sixth Mass Extinction
1. Over the past 540 million years, the fossil record reveals five periods of extinction when 50–90% of living species suddenly died out.
2. Our current rate of extinction, over the past 400 years, indicates that we may be living in, and contributing to, the sixth mass extinction period.
3. Mass extinctions pave the way for the evolution of new and diverse forms, but it takes millions of years for Earth to recover. II. The Origin of Species
1. When Darwin visited the Galápagos Islands, he realized that he was visiting a place of origins.
a. Although the volcanic islands were geologically young, they were home to many plants and animals known nowhere else in the world.
b. Darwin thought it unlikely that all of these species could have been among the original colonists of the islands.
2. In the 150 years since the publication of Darwin’s book On the Origin of Species by Means of Natural Selection, new discoveries and technological advances have given scientists a wealth of new information about the evolution of life.
3. The diversity of life evolved through speciation, the process in which one species splits into two or more species.
A. What Is a Species?
1. Species is a Latin word…
