who is the father of evolution?

Galileo Galilei

Albert Einstein

Charles Darwin

Isaac Newton

what were the two main points Darwin made in the origin of species?

Organisms inhabiting earth today descended from ancestral species

Natural selection descent with modification

organisms did not descended from ancrestral species

no natural selection occurs on earth

what are the five lines of evidence in support of evolution

zoology, botany, ecology, microbiology, and astronomy

genetics, geology, meteorology, chemistry, and physics

paleontology, anthropology, psychology, sociology, and economics

fossil records, comparative anatomy, embryology, biogeography, and molecular biology

The deeper the rock layer of sedimentary rock layer represent?

Different geological formations

Higher pressure levels

Younger time periods

Older time periods

biogeography describes?

the distribution of species and ecosystems

the history of ancient civilizations

the study of rocks and minerals

the behavior of marine animals

comparison anatomy is the comparison of?

comparison of weather patterns

anatomical structures between different organisms

comparison of cooking techniques

comparison of historical events

homology is?

Similar structure due to shared ancestry

A type of mathematical equation

A method of plant propagation

A form of genetic mutation

comparative embryology is?

Study of adult organisms

Focuses on plant development only

comparison of early stages of
development in different animal species reveals common
evolutionary origins.

Involves studying fossils

what are molecular biology?

Evolutionary relationships
among species can be
determined by comparing
genes and proteins of
different organisms.

Molecular biology is the study of culinary arts

Molecular biology is the study of ancient civilizations

Molecular biology is the study of celestial bodies

10.

difference between convergent and divergent evolutions?

Convergent evolution involves unrelated species developing similar traits, while divergent evolution involves related species developing different traits.

Convergent evolution leads to the extinction of species, while divergent evolution promotes species survival.

Convergent evolution involves species evolving in the same direction, while divergent evolution involves species evolving in opposite directions.

Convergent evolution involves related species developing similar traits, while divergent evolution involves unrelated species developing different traits.

11.

what are the four processes that causes evolution to occur?

genetic variation, genetic mutation, gene drift, natural selection

mutation, gene flow, genetic drift, and natural selection

variation, genetic mutation, gene flow, natural selection

mutation, gene flow, genetic variation, artificial selection

12.

mutation is?

A new type of computer

A type of weather phenomenon

A change in the DNA sequence of an organism.

A type of flower

13.

genetic drift is?

Random change in allele frequencies in a population over time due to chance events. Reduced variations in gene pool

An abrupt change in allele frequencies caused by mutation

A gradual change in allele frequencies due to natural selection

A process that intentionally selects for specific alleles in a population

14.

what is the bottleneck effect of genetic drift

Increase in population size leading to loss of genetic diversity

Decrease in population size leading to increased genetic diversity

No impact on genetic diversity due to population size changes

Reduction in population size due to environment factors leading to loss of genetic diversity and increased frequency of certain alleles

15.

what is the founder effect in genetic drift?

Loss of genetic variation in a new population since a small group of individuals colonize a new region

Founder effect is a result of natural selection, not genetic drift.

Increase of genetic variation in a new population established by a small group of individuals from a larger population.

Founder effect only occurs in plants, not animals.

16.

example of genetic drift?

Mutation

Bottleneck effect

amish people

Natural selection

17.

what is gene flow?

Gene flow is the transfer of genetic material from one individual to another within the same population.

Gene flow is the process of genetic material being passed down from parent to offspring.

Gene flow is the movement of genes between different species.

Gene flow is the transfer of genetic material from one population to another through migration and interbreeding.

18.

what is natural selection?

Natural selection is the process where organisms randomly evolve.

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Natural selection is the process where organisms adapt to their environment by choice.

Natural selection is the process of humans selecting which organisms survive.

19.

what are sexual selection?

Sexual selection is a form of natural selection in which
individuals with certain traits are more likely than other
individuals to obtain mates.

Sexual selection is a method used in agriculture to improve crop yields

Sexual selection is a type of natural disaster that affects ecosystems

Sexual selection is a theory in chemistry that explains how atoms bond

20.

what are the three outcomes of natural selection?

artificial selection

directional selection, stabilizing selection, disruptive selection

random selection

evolutionary selection

21.

directional selection favors?

individuals at one extreme of a trait distribution (extreme phenotype)

individuals with random traits

individuals with average traits

individuals at the mean of a trait distribution

22.

stabilizing selection favors?

Intermediate phenotype, occurs in relatively stable environments, and is the most
common.

Unstable phenotype

Random phenotype

Extreme phenotype

23.

disruptive selection favors?

average phenotypes

can lead to a balance between two
or more contrasting phenotypic forms in a population (ex: small and large fish in terms of survival)

random selection

non-phenotypic traits
