Flashcards in classification and evolution definitions Deck (18):
1

Binomial naming system

A system which uses the genus name and the species name to avoid confusion when naming organisms

2

Classification

The process of placing living organisms into similar groups based on their similar characterstics

3

Phylogeny

The study of the evolutionary relationship between organisms

4

Natural selection

the term used to explain how features of the environment apply a selective force on the reproduction of individuals in a population

5

continuous variation

variation where there are two extremes and a full range of values in between

6

discontinuous variation

where there a distinct categories and nothing in between

7

environmental variation

variation caused by response to environmental factors such as light intensity

8

Genetic variation

variation caused by possessing a different combination of alleles

9

Interspecific varaiton

the differences between different species

10

interaspecific variation

the differences between individuals belonging to the same species

11

Variation

the presence of variety - the differences between individuals

12

Correlation Coefficient

A measure of how closely two sets of data are correlated - a value of 1 is perfect correlation

13

Standard Deviation

a measure of the spread around a mean

14

Students T- test

a test used to compare two means

15

Adaption

A characteristic that enhances survival in the habitat

16

Anatomical adaptations

structural features of an organism that enhances survival in a habitat

17

Behavioural adaptations

the ways that behaviour is modified for survival

18

Physiological/Biochemical adaptations

affect the way that ell processes work that enhances survival in a habitat
