17
Q

what is divergent evolution?

A

the evolution of many different things. (homologous)

18
Q

what is convergent evolution?

A

independent evolution in different species that gives rise to similar functions. (analogous)

19
Q

what is embryology?

A

the study of the formation and development of an embryo and fetus

20
Q

what are fossil records?

A

all the fossils that have been found, along with their relative ages

21
Q

what is lamarck’s theory of evolution?

A

anything that happens to a parent during its life is passed onto its offspring

22
Q

what is spontaneous generation?

A

the belief that living things arose from non-living things

23
Q

what is darwin’s theory of evolution?

A

those with reproductive/genetic success will pass on the preferred variation to their offspring through a process of elimination

24
Q

what is beneficial mutation?

A

mutations that enhance an organism’s fitness (reproductive success)

25
Q

what is harmful mutation?

A

mutations that reduce an organism’s fitness (reproductive success)

26
Q

what is neutral mutation?

A

a mutation that does not affect an organism’s fitness (reproductive success)

27
Q

what is a homologous feature?

A

features with similar structures but different functions

28
Q

what is an analogous feature?

A

features that are similar in appearance but don’t have the same evolutionary origin

29
Q

what is natural selection?

A

reproductive success of individuals caused by variation in their inherited characteristics

30
Q

what is artificial selection?

A

the process of human selecting and breeding individuals with desired traits

31
Q

what is survival of the fittest?

A

organisms with successful genes/traits will outlive those without them and pass the traits down to offspring

32
Q

what is sexual reproduction?

A

production of offspring by two parents, in which offspring have genes from both parents

33
Q

what is asexual reproduction?

A

production of offspring from one parent, offspring are all identical

34
Q

what is the theory of gradualism?

A

the idea that speciation occurs slowly

35
Q

what is the theory of punctuated equilibrium?

A

the idea that species evolve rapidly, followed by a period of little to no change

36
Q

what is speciation?

A

a group within a species separates from other members of its species and develops its own unique characteristics

37
Q

what is allopatric speciation?

A

occurs when a species separates into two separate groups that are isolated from one another

38
Q

what are vestigial features?

A

structures with no useful function

39
Q

what is a species that is only found in one location?

40
Q

what is biogeography?

A

the study of the geographic distribution of life on earth

41
Q

what is the difference between archaebacteria and eubacteria?

A

eubacteria’s cell wall contains peptidoglycan whilst archaebacteria’s cell wall does not

42
Q

what acronym is used for the taxa categories?

A

king (kingdom) philip (phylum) can (class) only (order) find (family) green (genus) shoes (species)
