Evolution 2 (By Mr, O)

Front 1

law

Back 1

explains what happens

Front 2

theory

Back 2

explains why or how something happens

Front 3

evolution

Back 3

a change in a gene pool of a population over time

Front 4

natural selection

Back 4

organisms with genes that are best suited for their environment are more likely to survive and reproduce

Front 5

DNA

Back 5

carries the blueprint to make proteins

Front 6

chromosomes

Back 6

contains your genetic information- who you are

Front 7

mutation

Back 7

a mistake (or change) made when your DNA is being copied

Front 8

microevolution

Back 8

small changes

Front 9

macroevolution

Back 9

large scale changes - typically resulting in a new species forming

Front 10

convergent

Back 10

the process by which unrelated species become more similar as they adapt to same environment

Front 11

geographic isolationn

Back 11

physical separation of a group of individuals from others of the same species

Front 12

gradualism

Back 12

the theory that evolution occurs slowly but steadily

Front 13

punctuated equilibrium

Back 13

fast evolutionary change

Front 14

selective breeding

Back 14

breeding closely related species to get traits people want

Front 15

gene

Back 15

a section of DNA that codes for a trait; like hair color or eye color

Front 16

Evolution in a nutshell: 1st step

Back 16

genes mutate

Front 17

Evolution in a nutshell: 2nd step

Back 17

individuals are selected

Front 18

Evolution in a nutshell: 3rd step

Back 18

population evolves

Front 19

Reasons why a non-beneficial trait would be selected

Back 19

The people who have trait may reproduce before death; Trait may be linked with a beneficial trait

Front 20

survive and reproduce

Back 20

If you are selected that means you...

Front 21

the environment, your own species, having an advantageous trait

Back 21

You are selected by...

Front 22

overproduction

Back 22

when a species produces far more offspring than needed, increasing the chance that their genes will continue to the next generation even if many are killed
off

Front 23

disadvantages for overpopulatio
n

Back 23

spread diseases easier, not enough food

Front 24

acquired characteristics

Back 24

traits, skills or body language changes you gain during your life but cannot be passed to your children

Front 25

GMO'S

Back 25

(genetically modified organisms) when selective breeding occurs in cats, dogs, horses and other animals as well as plants, creating this

Front 26

instinct

Back 26

the internal mechanism that drives natural selection is the ________ to pass on one's genes
