Evolution

Question 12

______________________, was the first biologist to believe that life forms do evolve.

Answer 12

Jean Baptiste de Lamarck

Question 13

He proposed the inheritance of acquired characteristics,
which is also called as the ___________ _________.

Answer 13

Lamarckian Evolution

Question 14

________ ______ published his book, On the Origin of Species by Means of Natural Selection.

Answer 14

Charles Darwin

Question 15

Charles Darwin was only 22 years old when he got a chance to set sail
aboard the _________ to travel around the world and map the coasts of South America.

Answer 15

Beagle

Question 16

His Beagle voyage allowed him to develop a theory that would contradict the special
creation of every organism and imply that all species evolved from a common ancestor through a process called ________ ______.

Answer 16

natural selection

Question 17

_______ is a set of genetically acquired traits that makes organisms better suited to their
environment.

Answer 17

Adaptation

Question 18

________ are examples of evidences that paleontologists use in studying evolution. They are traces of
organisms that lived in the past and were preserved by natural process or catastrophic events.

Answer 18

Fossils

Question 19

This method is used to determine the age of rocks by comparing them with the rocks present in the other layer. The younger sedimentary rock layer is assumed to be found on top and the older rock is found at the bottom layer

Answer 19

Relative Dating

Question 20

This type of dating is used to determine the age of rocks using the decay of radioactive isotopes present among the rocks such as Carbon-14. All organisms have decaying Carbon-14 in them.

Answer 20

Radiometric Dating

Question 21

It is used to tell the age of organic materials. Art collectors use carbon dating to determine if a piece of artwork is genuine or not.

Answer 21

Carbon Dating

Question 22

Precambrian, Paleozoic,
Mesozoic, and Cenozoic.

Answer 22

Geologic Time Scale

Question 23

These refer to structures from
different species which have similar internal framework,
position, and embryonic development. Homologous structures may have the same origin or ancestors but different functions. This type of evolution is called divergent evolution. The forelimbs belonging to a dog, man,
cat, bat, bird, lizard, and whale are structurally the same, but
are functionally different.

Answer 23

Homologous structures

Question 24

The structures of unrelated species may evolve for them to look somewhat the same because the structure has adapted to similar functions. In another words, analogous structures have similar functions but different in origin. In convergent evolution, analogous structures of unrelated organisms from different ancestors developed a similar function. Example: The wings of birds, bats, and insects exhibit the same functions.

Answer 24

Analogous structures

Question 25

Organisms are part of biodiversity and may be economically and ecologically valuable. Their products are a source of food, medicine, clothing, shelter, and energy. They are important in maintaining the balance in the ecosystem as they perform their specific roles.

Answer 25

Ecosystem

Question 26

is the variety of life on earth and the essential interdependence of all living things. Short for biological diversity, includes all organisms, species, and populations; the genetic variation among these; and all their complex assemblages of communities and ecosystems. It also refers to the interrelatedness of genes, species, and ecosystems and their interactions with the environment.

Answer 26

Biodiversity
