Allopatric
Speciation due to organisms of a species being separated by geographical barriers so that over time members of the two populations become so different that they cannot interbreed and are considered to be two different species
1 of 22
Artificial Selection
Process of improving a variety of crop plant or domesticated animal by breeding from selected individuals with desired characteristics
2 of 22
Biodiversity
Number and variety of living things to be found in the world, in an ecosystem or habitat
3 of 22
Class
Taxonomic group used in classification of living organisms. Members of the same class share some characteristics. Within each class are orders, consisting of families, genera and species. Similar classes grouped into a phylum
4 of 22
Conservation ex situ
Conservation in areas other than the natural habitat
5 of 22
Conservation in situ
Conservation in natural habitat
6 of 22
Domain
Classification group. Carl Woese's three-domain classification system divides the Kingdom Prokaryote into two domains and places all Eukaryotes in the third domain
7 of 22
Ecosystem
All living organisms and all non-living components in a specific area and their interactions
8 of 22
Evolution
Gradual process by which present diversity of living organisms from simple primitive organisms that were present about 400 million years ago. New species have arisen by natural selection.
9 of 22
Genus
Taxonomical group used in the classification of living organisms. Species that are similar are placed in the same genus
10 of 22
Heterotroph
Organism that gains nutrients from complex organic molecules
11 of 22
Monoculture
Crop of plants of a single species bred to be very similar
12 of 22
Monophyletic
Group of organisms is said to be monophyletic if they share common ancestor + therefore belong to same classification group
13 of 22
Order
Similar families are placed in the same order
14 of 22
Phylogeny
Evolutionary relationships between organisms
15 of 22
Selection Pressure
External pressure that drives evolution in a particular direction
16 of 22
Sustainable Development
Development that doesn't cause excessive harm to the surrounding environment
17 of 22
Speciation
Formation of a new species
18 of 22
Sympatric
Speciation occurs within one area- some factor other than geographical separation has prevented free interbreeding between members of the species
19 of 22
Taxonomy
Study of the principles behind classification
20 of 22
Biological Classification
Process of sorting living things into groups. Natural "" does this by grouping things according to how closely related they are and reflects evolutionary relationships
21 of 22
Variation
Differences between individuals
