The science that deals with structures, Functions of living things and their relationship with the environment
Biology
3 MAJOR DIVISIONS OF BIOLOGICAL SCIENCE
- Microbiology
- Botany
- Zoology
Study of naming and classifying organisms
Taxonomy
Study of structures and functions of cells
Cytology
Study of formation and development of organisms
Embryology
Study of structures and parts of organisms
Anatomy
Study of functions of living organisms and their parts
Physiology
Study of biochemical compositions and processes of living things
Biochemistry
Study of heredity and variation
Genetics
Study of origin and differentiation of various organisms
Evolution
Study of relationships of organisms with each other and their environment
Ecology
Study of biological data using computer programs
Bioinformatics
Study of the entire genetic material of an organism
Genomics
Study of molecules that make up the cells of living organism
Molecular biology
Study of how genes affect a person’s response to drugs
Pharmacogenomics
Study of the different proteins in an organism
Proteomics
Study of artificial biological systems
Syntactic biology
Study of computational and mathematical modeling of biological systems
Systems biology
Human taxonomy
- domain
- Kingdom
- phylum
- Order
- Family
- Genes
- Species
In a biological point of view science is a body of systematic information about living things derived from observation and experiment
Biology as a science
Two main approaches in scientific investigation
- Discovery
- Hypothesis
Base science relies mainly on verifiable observations and measurement
Discovery
Base science involves the use of scientific method which is used as a guide by biologists in solving problems
Hypothesis
The scientific method Involved several steps enmurate
- Observation
- Hypothesis
- Experiment
- Conclusions
Identifying and clearly defining a problem
observation
Formulating a possible logical answer to the identified problem
Hypothesis
Two kinds of scientific reasoning
- Inductive Reasoning
- Deductive Reasoning
Scientific reasoning from specific to general
inductive reasoning
use as a bottom up approach
Inductive reasoning
Allows biologists to formulate a tentative hypothesis
Inductive reasoning
top down approach
Deductive reasoning
General to specific
Deductive reasoning
Used by biologists to test existing theories or hypotheses
Deductive reasoning
Conducting controlled attempts to test One or more hypothesis and includes recording and analyzing results
experiment
Experimental data are analyzed to reach a conclusion
Conclusions
Propose the theory of spontaneous generation
Aristotle
Idea that living things can arise from nonliving matter also called as spontaneous generation
Abiogenesis
The belief that life originates from preexisting life
Biogenesis
in 1668, an Italian physician did an experiment with flies and wide mouth jars containing meat
Francisco Redi
the scientific method used by Francisco Redi
- Observation
- Hypothesis
- Experiment
- Accept, Reject, or Modify Hypothesis
Need a new microscope for each specimen
Anton Van Leeuwenhoek (1647)
The examiner water and visualized tiny animals Hyundai Algae and single called Protozoa also known as
animalcules
By the end of 19th century these organisms were called
Microbes
He shared that my hair organisms flourished in various soups that had been exposed to the air
John Needham (1745)
Claim that there was a life force present in the molecules of all inorganic matter including air and the oxygen in it
John Needham (1745)
He supported the spontaneous generation or abiogenesis
John Needham (1745)
Boiled soups for almost an hour and sealed containers by melting the slender necks closed
Lazzaro Spollanzani’s (1765)
in ______ the debate had become so heated that the Paris Academy of Sciences offered a prize for any experiments that would help resolve this conflict on how microbes arise
1860
The price from the Paris Academy of Sciences was claimed by
Louis Pasteur
He was the only one to To support that abiogenesis
John Needham (1745)
The oldest hypothesis that life came from a divine being is the most widely accepted belief
Divine Creation
Patientists believe that everything was made by a supreme being in a six day period
Divine Creation
It was believed that life came from a _____________ ________or life evolved from inanimate matter
Spontaneous Origin
This proposes that a meteor or cosmic dust may have carried to a significant amount of organic molecules which started the evolution of life
Panspermia
