Taxonomy and origins

Terms in this set (26)

Animal husbandry
The science of controlling or improving certain features of livestock their genetic breeding programs.
Archeology
The science of research and study of artifacts and ancient cultures
Artificial system
In taxonomy, a classification plan based on grouping certain outstanding features of plants or animals
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 that brought the first "living "cell from nonliving can. From the starting point organisms have increased and complexity and variety
Natural system
And 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 feelings of the scientist.
Origin
The beginning. I'm coming into existence or being. The beginning of the earth or the universe.
Philosophy
O 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.
Speciation
Development of new species and new kinds from an ancestral species. A concept of evolution.
Verify
To test the truth or accuracy. To prove accuracy or truth by evidence.
T or F? A person's views on origins may be greatly influenced by embracing a particular taxonomic system
True
When a system of classification is based on observation of a predetermined set of factors, it is called:
An artificial system
T or F? If the theory of evolution were true it would not be possible to classify organism into distinct categories
True
Why have the gaps among existing organisms as well as the fossil records remain 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 taxes due to the persistence of gaps.
What is meant by "gaps" within living things are fossils?
Missing links. A distinct and obvious lack of transition between all higher levels of taxa.
The science of genetics has demonstrated repeatedly
That variation among species is not the result of evolution
On artificial system looks at ______, while a natural system looks at ______.
Morphology and common ancestors
Two practices which have helped in the development of understanding the variation 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.
