Table of Contents
Which features of DNA is most important in determining the
phenotype of an organism?
A Particular strand of DNA has the base sequence ATT-CCG. What is the base sequence of the complementary strand?
Why will knowledge of the human genome enable scientist to better understand proteins involved in human diseases?
a. DNA contains the information used to make proteins.b. Nucleic acid molecules have shapes similar to those proteinsc. The bases that make up DNA are also present in RNAd. Chromosomes can combine to form proteins
Exploring Evidence of Evolution: Starter
The sequence of nitrogenous bases
TAA-GGC
What is a fossil? The remains or
impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock
Practice
Fossils provide
evidence that life on Earth has changed as well as evidence about how that change has occurred. They also provide evidence of common ancestry among organisms.
Fossils and Evolution
Radiometric
dating tells us how old fossils are and where they fit in Earth’s timeline. Radiometric dating also gives us the relative age of the Earth.
Fossils and Radiometric Dating
The study of how species
are scattered across the planet and our understanding of plate tectonics provide us with evidence that evolution and natural selection have been shaping life on Earth for millions of years
Evolution and Biogeography
Examples of homologies (such as
the claws of Hoatzin chicks and eggs of platypus) give us examples of intermediate organisms (organisms that have features similar to two totally separate groups of organisms).
Organisms that have features homologous to the features of other living organisms, as well as to fossils, provide evidence that organisms living today are linked to each other through common ancestors
Evolution and Homologies
Instructions Fill in the graphic organizer on your handout by clicking
through the next slide. Each topic (textbox) in the graphic organizer is
hyperlinked to a webpage that gives you information and explanations about that topic.
In slide show view, move the mouse over the topic and click. This will take you to the linked webpage.
Analyze and evaluate the information on each webpage. Use that information to answer the questions on your
student handout. Although all answers can be found within the
information on the linked web pages, other web resources may be used if needed.
