adaption/modifications

changes in the occurrence of genetic traits in a population due to natural selection resulting in the transformation of all life over long periods of time

1

homologous structure

similar structures in species sharing a common ancestor

2

CCR5

protein receptor on the surface of a white blood cell used as a doorknob that allows HIV to enter the blood stream.

3

homeotic gene

master control genes that direct development of body parts in spevofic locations in many organisms.

4

binomial nomenclature

naming system developed by Linnaeus
system of naming organisms with 2 names

5

Linnaeus

came up with naming system

6

order of generalized

Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

7

three kinds of domains

archaea
bacteria
eukaryotes

8

binomial

genus
species

9

father of taxonomy

linnaeus

10

scientific name

the 2 names used globally to refer to a life form

11

human classification

animal
chordate
mammalia
primate
hominid
homosapien

12

taxonomy

the study of naming all organisms and placing them in groups

13

homologous structure

similar structures found in more than one species that share a common ancestor

14

example of homologous structure

bones in humans, whales, dogs and bat forelimbs

15

vestigial structures

remnant ofa structure that may have had larger function in a species ancestors but has a lesser function today

16

body parts that suggest common ancestory due to similar structure

homologous structures

17

homeotic genes that control the body part development and influence evolution evolution of traits like neck length are called

hox genes

18

evolution

changes in the occourences of genetic traits in a population due to natural selection resulting in the transformation of all life over long periods of time

19

what did darwin call evolution

decent with modification

20

name of darwins book

origin of species

21

natural selection

process by which individuals with inherited characteristics, well suited to their environment leave more offspring than others

22

lyell

proposed that gradual process (erosion) explain the physical features of todays earth

23

radiometric dating

uses mathematical formulas to study the amount of radioactive isotopes in a fossil

24

why do isotopes decay

because they are unstable. too many neutrons break nucleus

25

half life

the amount of time that it takes half a radioactive isotope to decay into a new stable element

26

gradualism

the theory that the earth has been slowly shaped by natural forces
(lyell)

27

continental drift/ pangea

the worlds continents as a giant land mass (pangea) separated

28

fossil examples

piltdown fossil
otzi
sue

29

types of fossils

tar
amber
sedimentary rock
petrification

30

artificial selection

selective breeding to produce offspring with traits that humans value

31

how long ago was the big bang

14 billion years ago

32

classification

the part of taxonomy where life forms are grouped with others with similar ancestors or similar genetic make up

33

overpopulation/competition

human suffering due to the fact that population grows faster tgat resources can be produces

war famine disease

34

who recognized consistencies in rat population but nit humans? overpopulation

thomas malthus

35

charles darwin

father of evolution

36

early ideas before darwin

young earth
unchanging

37

HMS beagle

dariwns ship to galapagos

38

adaptation

hen organisms spread into mew habitats and accumulate modifications

39

fossils

preserved remains of early life forms

40

relative dating

estimates the age of a fossil based on its placement in layering rock

41

paleontology

the branch if science concerned with fossils

42

wallace

own theory of evolution around the time of darwin

43

Lamaitre

big bang theory
catholic priest

44

big bang theory

the universe was created when a large explosion created matter and space of the universe

45

evidence of big bang

universe is still expanding which can be seen by studying other galaxies in finding away
