BIOLOGY - UNIT 1: TAXONOMY: KEY TO ORGANIZATION TAXONOMY AND ORIGINS

Terms in this set (19)

animal husbandry
The science of controlling or improving certain features of livestock through genetic breeding programs.
archaeology
The science of research and study of artifacts and ancient cultures.
artificial system
In taxonomy a classification plan based on grouping by certain outstanding features of a plant or animal.(morphology)
economic uses
Plants or animals selected or sorted from others on the basis of certain features which are salable. Food and clothing, plants and animals are bought, sold, and traded.
evolution
A model of origins based on the theory that random natural processes produced the first "living" cell from nonliving chemicals. From this starting point organisms have increased in complexity and variety.
natural system
In taxonomy, a classification plan based on assumed relationships of common ancestry or evolution.
objectivity
Without bias. Thoughts or interpretations based on the features and characteristics of the organism, instead of on the feelings of the scientist.
origin
The beginning. A coming into existence or being. The beginning of the earth or the universe.
phylosophy
A body of ideas based on personal opinion.
plant breeding
The science of controlling or improving certain features of crops and vegetables through genetic breeding programs.
specification
The development of a new species and new kinds from an ancestral species. A concept of evolution.
verify
To test for truth or accuracy. To prove accuracy or truth by evidence.
When a system of classification is based on observation of a predetermined set of factors, it is called:
an artificial system
A natural taxonomic system currently in use attempts to show:
ancestry of ganisms
family trees
genetic relationships
evolutionary descent
Observations from plant breeding and animal husbandry over thousands of years has shown:
variations are limited to the confines of lower taxa

observable changes from one basic kind into another have never been documented
Why have the gaps among existing organisms as well as the fossil records remained after hundreds of years of research?
because distinct populations of living things exist due to barriers to reproductive change
because fossils may be classified into distinct taxa due to the persistence of gaps
What is meant by "gaps" within living things or fossils?
missing links
a distinct and obvious lack of transition between all higher levels of taxa
Two practices which have helped in the development of understanding the variations within "kinds" of living things are animal husbandry and .
genetics
If the theory of evolution were true, there would be records of observable changes between the basic of organisms
kinds
