Lab 1: Observing Evolution in regards to The Volvicine line and Defining a Niche at AU Objective: The objective of this lab was to help us better understand natural selection and to help us understand the biotic and abiotic characteristics of a niche. The purpose of the lab was to view a multicellular organism and see how it originated and evolved from once a single celled organism to where it is today. We viewed this from the origin of a volvocine line where we saw the complexity of cells increase from Chlamydomonas to genius's to volvox, the most complex. Additionally we were group #2 so we were in charge of niche #2, we created our hay infusion in order to study bacteria in the following week. If the volvicine line truly does exhibit natural selection and evolution the complexity of the cells ranging from Chlamydomonas to Gonium to Volvox will become increasingly complex. Steps:

          Procedure 1: The Volvicine Line

1) We took Chlamydomonas and prepared a slide and included Protoslo 2) We observed through a microscope and saw that they were round and not grouped together 3) We prepared our Gonium slide and added protoslo 4) We observed through a microscope and saw that they were some-what grouped up with 4-5 cells per group/colony. 5)We prepared a Volvox slide and added protoslo 6) We observed through a microscope and saw that there were thousands of cells and were grouped together.

          Procedure 2: Defining a Niche at AU

1) We were assigned transect #2 which was near the seminary 2) We traveled to transect #2 3) We observed the niche and saw that this specific niche was more isolated then others 4) We took sample data which was 1/2 soil 1/2 plant matter and took it back to the lab. 5) When we arrived in lab we created a hay fusion which involved: 6) Weighing 11.2 grams of soil/ground sample and placing it in a plastic jar with 500 mld of deer park water 7) adding .1 grams dried milk and mixing for 10 seconds 8)Label Jar 9) Place jar in corner of the room with top off Raw Data:
