BIO-112 Biology II-Science

Dr. Christy Beal

[email protected]

Course Description

• This second semester continues the basic

principles explored in Biology I and examines

members of the animal kingdom with particular

emphasis on mammalian anatomy and

physiology. Laboratory work complements the

lecture material.

• Prerequisites: ENG-013, ENG-023 and MTH-

029

• We will have a short lecture at the beginning of most labs. We have about 2 hours of lecture and 4 hours of lab a week

• You are expected to attend all lectures and labs!

• Read assigned readings prior to coming to class.

• Read over the syllabus, and ask questions! All

lectures, handouts and helpful links are online

at http://bealbio2.weebly.com/

Course Description

Grading

• Grades are based on exams, quizzes and lab work.

1. 4 exams worth 100 pts each = 400 pts

2. Lab practicals and exercises = 180 pts

3. Final Project = 50 pts

Total points for this course = 650 points

Final Project

• This project is designed to have you synthesis

some of the main ideas in this course and tie

them together.

• You have a lot of creative freedom but…

– Everything must be referenced

– You must complete the project by April 29th

Final Project – Choice 1

• Comparative anatomy

• Compare and contrast your choice of three (3)

systems that we covered (ie circulatory,

excretory, nervous) between two groups (phyla

or class) AND humans. What are the

similarities, differences? How does the animal's

structure reflect the functions of each system?

Final Project – choice 2

• Detailed exploration of 1 group (phyla or

class)

• Include the taxa's classification, body plan and

characteristics, feeding, breeding, specific

adaptations and detail at least 5 subgroups for

your group. Pictures and/or diagrams must be

included and properly referenced.

Finally…

Ask me if you have any questions!

Chapter 1: Inquiring About the World of Life

• Evolution is the process of change that has transformed life on Earth

• Biology is the scientific study of life

• Biologists ask questions such as:

– How a single cell develops into an organism

– How the human mind works

– How living things interact in communities

• Life defies a simple, one-sentence definition

• Life is recognized by what living things do

Concept 1.2: The Core Theme: Evolution accounts for the unity and diversity of life

• “Nothing in biology makes sense except in the

light of evolution”—Theodosius Dobzhansky

• Evolution unifies biology at different scales of

size throughout the history of life on Earth

Organizing the Diversity of Life

• Approximately 1.8 million species have been

identified and named to date, and thousands

more are identified each year

• Estimates of the total number of species that

actually exist range from 10 million to over 100

million

Taxonomy is the branch of

biology that names and

classifies species into groups.

Domains, followed by kingdoms,

are the broadest units of

classification

The domain Eukarya

includes three

kingdoms:

– Plantae

– Fungi

– Animalia

There are 3 domains

Domain Bacteria and domain

Archaea comprise the

prokaryotes

Domain Eukarya includes all

eukaryotic organisms

Unity in the Diversity of Life

• A striking unity underlies the diversity of life

– DNA is the universal genetic language

common to ALL organisms

The Tree of Life

• “Unity in diversity” arises from “descent with

modification”

– For example, the forelimb of the bat, human,

horse and the whale flipper all share a

common skeletal architecture

• Fossils provide additional evidence of

anatomical unity from descent with modification

You should now be able to:

1. Briefly describe the unifying themes that

characterize the biological sciences

2. Distinguish among the three domains of life,

and the eukaryotic kingdoms

3. Know the major expectations of this course!
