Evolution

Front 13

Darwin did not just propose that organisms evolved. He also proposed a mechanism for evolution: _______.

Back 13

Natural Selection

Front 14

In the 1850, he wrote an influential and controversial book, “Origin of Species by Means of Natural Selection”

“Origin of Species by Means of Natural Selection”

Front 16

Only those who are tough enough will endure any given situation

Back 16

Survival of the fittest

Front 17

• In living organisms, many characteristics are inherited, or passed from parent to offspring.

Back 17

Traits are often heritable

Front 18

• Organisms are capable of producing more offspring than their environments can support. Thus, there is competition for limited resources in each generation.

Back 18

More offspring are produced than can survived

Front 19

• The offspring in any generation will be slightly different from one another in their traits (color, size, shape, etc.), and many of these features will be heritable.

Back 19

Offspring vary in their heritable traits

Front 20

occurs whenever a mistake in the DNA occurs in the heritable cells of an organism.

Back 20

mutation

Front 21

— also called migration — is any movement of individuals, and/or the genetic material they carry, from one population to another

Back 21

Gene flow

Front 22

is the term biologists use to describe the gradual loss of certain genes from a species–genes that may have been very important for that species’ survival

Back 22

Genetic drift

Front 23

farmers and breeders were using the idea of selection to cause major changes in the features of their plants and animals over the course of decades

Back 23

Artificial Selection

Front 24

is the scientific study of diversity of organisms and their evolutionary relationships.

Back 24

Systematics

Front 25

The branch of systematics that involves the study of naming, describing, and classifying organisms is called _____.

Back 25

taxonomy

Front 26

The person that studies Scientific Names

Back 26

Taxonomists

Front 27

Organisms are named using the binomial nomenclature system. It is a system in which an organism is given a two-part name consisting of genus and species

Population

Front 31

VARIABLES ACCOUNTED FOR CHANGES IN POPULATION SIZE

Back 31

Front 32

The ability or capacity of a population of a species to grow or propagate under ideal environmental conditions--- given sufficient food supply, no diseases and no predators present

Back 32

Biotic Potential

Front 33

The combination of all factors to limit growth of a population, Prevents populations from reaching their full biotic potential

Back 33

Environmental Resistance

Front 34

• their effects are most pronounced when the population density increases beyond a certain level, in other words, whose effects on the size or growth of the population vary with the population density.

Back 34

Density Dependent

Front 35

can affect the population without being necessary based on the density.

Back 35

Density Independent

Front 36

- is defined as the maximum population of a given species that a particular habitat can sustain indefinitely without being degraded.
