Question 1

1. Adaptation

Answer 1

Nicolas Cage is Charlie Kaufman, a confused L.A. screenwriter overwhelmed by feelings of inadequacy, sexual frustration, self-loathing, and by the screenwriting ambitions of his freeloading twin brother Donald (Nicolas Cage).

Question 2

2. Species

Answer 2

In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.

Question 3

3. Evolution

Answer 3

Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.

Question 4

4. Fossil

Answer 4

Fossil Group, Inc. is an American fashion designer and manufacturer founded in 1984 by Tom Kartsotis and based in Richardson, Texas. Their brands include Fossil, Relic, Michele Watch, Skagen Denmark, Misfit, WSI, and Zodiac Watches.

Question 5

5. Fossil Record

Answer 5

The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.

Question 6

7. Selective Breeding

Answer 6

Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

Question 7

8. Natural Selection

Answer 7

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.

Question 8

9. Generation time

Answer 8

In population biology and demography, generation time is the average time between two consecutive generations in the lineages of a population. In human populations, generation time typically ranges from 22 to 33 years.

Question 9

10. Speciation

Answer 9

Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.

Question 10

11. Relative Dating

Answer 10

Relative dating is the science of determining the relative order of past events, without necessarily determining their absolute age. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.

Question 11

12. Absolute Dating

Answer 11

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word “absolute” implies an unwarranted certainty of accuracy.

Question 12

13. Geologic Time Scale

Answer 12

The geologic time scale is a system of chronological dating that classifies geological strata in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history.

Question 13

14. Extinct

Answer 13

Extinction is the termination of a kind of organism or of a group of kinds, usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point.

Question 14

15. Plate Tectonics

Answer 14

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up Earth’s lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century.

Question 15

16. Primate

Answer 15

A primate is a eutherian mammal constituting the taxonomic order Primates. Primates arose 85–55 million years ago first from small terrestrial mammals,

Question 16

17. Hominid

Answer 16

The Hominidae, whose members are known as great apes or hominids, are a taxonomic family of primates that includes eight extant species in four genera: Pongo; Gorilla; Pan; and Homo, of which only modern humans remain.

Question 17

18. Homo sapiens

Answer 17

Early modern human or anatomically modern human are terms used to distinguish Homo sapiens that are anatomically consistent with the range of phenotypes seen in contemporary humans from extinct archaic human species.
