• 3 DOMAINS
• major genetic differences
• continually refined
• phylogenetic tree
•What is an abstract? (page 30)
•Read “Birds –In a Class of Their Own,”pages 30-31 in the textbook
Birds are very unique organisms. Even with their distinguishable
characteristics, their evolutionary history has left multiple scientists
challenged to nail down their ancestral heritage.
Part of being a good student and strong scientist is to look at the
newest information, but also take into account the work of previous
scientists. After completing the reading, you are to write a
paragraph explaining how the accumulation of evidence can refine
scientific understanding (use the work done with birds as evidence
for your argument).
What makes a good scientific paragraph?
-succinct
-specific
-relies on evidence
