8.L.4 Vocabulary

the STUDY of how characteristics of living things are transmitted (passed) from one generation to the next.

• evolution
• natural selection
• genetics
• taxonomy

how living things change over time

• evolution
• natural selection
• variation
• embryological

branch of biology that deals with the formation, early growth and development of living organisms (offspring)

• taxonomy
• embryological
• homologous structures
• domain

all organisms are grouped into 3 large groups using things they have in common (the groups are: bacteria, archaea, eukarya)

• class
• phyla 
• kingdom
• domain

process where animals adapt to their environment in order to survive (survival of the fittest)

• adaptation
• natural selection
• analogous structures
• domains

grouping of things by their common traits

• evolution
• natural selection
• analogous structures
• taxonomy

2 organisms having similar body parts because they were needed since they lived similar lives (example: bee wings and bird wings because they need to fly)  It is not from an ancestor they have in common.

• analogous structures
• homologous structures
• domains
• taxonomy

body parts on 2 completely different organisms that have similar structure and position on the body because of a common ancestor (example: arms of a person and front legs of a horse)

• adaptations
• variations
• analogous structures
• homologous structures

something slightly different from others of the same type (species) (example: eye color)

• adaptation
• variation
• natural selection
• taxonomy

evolutionary process where an organism becomes better suited to its habitat over time

• taxonomy
• genetics
• variation
• adaptation
