a bunch of proven hypothesis put together based off scientific evidence

Question 5

evolution is…

Answer 5

how an organism changed over time (due to DNA changes)

Question 6

all forms of life on earth are related by…

Answer 6

Common Ancestor that Inheritable Traits are passed down and some changes happen naturally or purposely (by humans) over time

Question 7

the earth is millions of years old, Principles of Geology

Question 9

Jean Baptiste Lamarck created what idea?

Answer 9

you can obtain traits, Species Modification

Question 10

Charles Darwin created what idea?

Answer 10

species vary globally, locally, and overtime, descent with modification, modification by natural selection

Question 11

species modification is…

Answer 11

similar species arose from common ancestor

Question 12

descent with modification

Answer 12

all life forms descended from one or few common types of life (apes -> humans)

Question 13

modification by natural selection

Answer 13

evolution happens due to DNA changes that are random

Question 14

3 facts of modification natural selection

Answer 14

1. more offspring produced than can survive
2. different traits can have better survival chances
3. parents are replaced by children that are better adapted

Question 15

adaption radiation

Answer 15

a process in which organisms diversify rapidly to form many new forms (particularly environmentally changes)

Question 16

artificial selection

Answer 16

nature provides varieties and humans select those they find useful

Question 17

homologous body structure

Answer 17

different form, Same function and tissue

Question 18

analogous body structure

Answer 18

same function different structure

Question 19

vestigial structure

Answer 19

things organisms have but doesn’t use anymore (ancestors used them) EX. wiggling ears

Question 20

similarities in embryology

Answer 20

embryos look similar, but similarities fade as development continues

Question 21

geographic distribution of living species

Answer 21

animals were exposed to similar pressures of natural selection and ended up evolving certain common features

Question 22

macro molecule and biochemical similarities

Answer 22

homologous proteins, RNA, DNA, ATP, CHONPS, carbohydrates, lipids, nucleic acids,

Question 23

Transitional species

Answer 23

many fossils show a clear distinction from one species to another
