Homework: finish lab 38
Today in class we started of with Mr. Paek checking to see if the homework worksheet from 16.4 was finished. We also handed in lab 13 pages 17-19 in the UP packet. Then we took notes in the packet called To Be Or Not To Be Evolution that we got a a couple days ago, and I will write those below;
C. Evidence for Evolution
1. Fossil Record
-ex. insects in amber, not complete,
-the record does indicate what did live at different times
2. Living Organisms
-Embryology
-development of embryo is very similar in different species.
-Body Structures
Homologous Structures
-bones in the legs and arms of vertebrates are very similar in structure but not always function.
Vestigial Organs
-organs that remain in an organism but seem to have no obvious function, e.x. appendix, muscles that move in the ear.
-Biochemistry
-similar chemicals found in living things: DNA sequence, blood antigens.
that was all we did for notes today.
After the notes we worked on Lab 38 from the lab books. the objective of this lab was to learn about homologous, analogous, and vestigial structures and their significance in evolution theory. the background includes that much evidence has been found to indicate that living things have evolved or changed gradually during their natural history. The study of fossils as well as work in embryology, biochemistry, and comparative anatomy provides evidence for evolution.
