1

Adaptive Radiation

The branching out of a population through variation and adaption to occupy many environments

2

Barrier

anything that prevents the spread of organisms to new environments

3

Binomial Nomenclature

the system used by scientists in naming organisms

4

Convergent Evolution

the process by which organisms of entirely different origin evolve in a manner that results in certain similarities

5

Corridor

a pathway that allows the spread of population to new areas

6

Embryology

the study of early developments of an organism

7

Era

a division of geological time of millions of years duration

8

Evolution

the slow process of change in which organisms arise, change, and become extinct over a period of time

9

Fossil

the hardened remains of an animal or plant embedded in rock

10

Homologous

parts of similar origin and structure but usually differing in function

11

Isolation

the confinement of a population to a certain location due to barriers

12

Kingdom

the largest classification group

13

Sedimentary

rock formed by the settling of minerals in bodies of water

14

Species

a group of organisms exhibiting the same characteristics and freely interbreeding

15

Sweepstakes Dispersal

Distribution of organisms to new areas despite strong barriers

16

Taxonomy

the science of classification

17

Vestigial

organs that are poorly developed or non-functioning

18

Lamarck always said...

That a child is strong because his dad lifted weights

19

Human Vestigial Organs are..

ear muscles, tail vertebrae, and nictitating membranes

20

Biochemical Similarity

similar hormones and enzymes in most mammals

21

All classification systems are..

Man made and artificial

22

The most accurate method of determining age is...

measuring the decay of radioactive elements

23

Linnaeus-

known as the father of modern taxonomy. He started using binomial nomenclature or two names to signify a species. However a major drawback of his way was that he believed that species were unchanging. he based all of his classifications on structural

24

Recombination increase..

the frequency of mutant genes in a population

25

The order of classification of animals from least specific to most specific are..

kingdom, phylum, class, order, family, genus, species

26

Most mutant genes are..

recessive and sometimes it takes many generations for them to be expressed.

27

isolation causes..

variations to be produced through new gene combinations.

28

environment,

number of offspring produced, and natural selection help drive evolutionary process

29

Only a germ mutation variation can..

lead to evolution of a species.

30

Environment determines..

the success or failure of a variation

31

Remember!

if all types of organisms that ever lived, were still living, you would have trouble in some cases of finding evidence of gradual transition from common ancestors to all existing forms of life.
