VOCAB

Question 1

Fossil

Answer 1

The hardened remains or imprint of a living thing that lived long ago.

Question 2

Embryo

Answer 2

An animal in the earliest stages of development, especially before it hatches, mammals, before it has reached a distinctly recognizable.

Question 3

Species

Answer 3

A taxonomic category of closely related organisms that are very similar to each other and are usually capable of producing fertile offspring when they breed with each other.

Question 4

Homologous Structure

Answer 4

Similar in structure and evolutionary origin, though not necessarily in function.

Question 5

Analogous Structure

Answer 5

Structures that are similar in function but having different evolutionary origins.

Question 6

Sedimentary Rock

Answer 6

formed from pre-existing rocks or pieces of once-living organism.

Question 7

Environment

Answer 7

All of the physical, chemical, and biological conditions that together affect an organism and influence its growth and development. Soil, air, water, climate, plant and animal life, and noise level are all components of an environment.

Question 8

Generation

Answer 8

A group of individuals or organisms all living at approximately the same time. The time span between the birth of the parents and that of the offspring.

Question 9

Population

Answer 9

All of the organisms of a species that live in a particular area.

Question 10

Individual

Answer 10

A single organism in a area

Question 11

Heritable

Answer 11

Capable of being passed from one generation to the next through the genes.

Question 12

Trait

Answer 12

A physical or behavioral feature of an organism, especially one that is determined largely by the organism’s genes.

Question 13

Natural Selection

Answer 13

The process in nature by which organisms that are better adapted to their environment tend to survive longer and produce more offspring than organisms that are less well adapted, so that the genetic characteristics of the better-adapted individuals become more widespread in later generations.

Question 14

Reproduction

Answer 14

To produce offspring

Question 15

Survival

Answer 15

The continuation of life or existence.

Question 16

Adaptation

Answer 16

Change or adjustment in structure or habits by which the members of a species become better able to function in their environment. Adaptation occurs during evolution through the action of natural selection. A structure or habit that results from this process.

Question 17

Survival of the Fittest

Answer 17

The natural process by which organisms best adjusted to their environment are most successful in surviving and reproducing.

Question 18

Extinction

Answer 18

No longer existing or living.

Question 19

Fitness

Answer 19

The quality or state of being fit. The capacity of an organism to survive and transmit its genotype to reproductive offspring as compared to competing organisms.

Question 20

Evolution

Answer 20

Change in the genes of a group of organisms over many generations, such that descendants are different from their ancestors.
