Define the term: Convergent Evolution

Convergent evolution is the process whereby organisms not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

Convergent evolution refers to the gradual change in a species over time due to natural selection and genetic drift.

Define the term: Coevolution

Coevolution is the influence of closely associated species on each other in their evolution.

Coevolution is the development of similar traits in unrelated species due to similar environments.

The scientific theory of evolution is backed by:

evidence from fossils, genetics, and comparative anatomy

Which of the following lists contains examples of advantageous traits that can spread over generations?

Camouflage, resistance to disease, sharp eyesight, fast running

Lack of camouflage, poor eyesight, slow running, susceptibility to disease

Genetic variation arises from:

mutations, genetic recombination, and independent assortment

When environmental conditions change, individuals with different genetic variations are:

more likely to survive and reproduce

Darwin’s finches are:

a group of birds studied by Charles Darwin in the Galápagos Islands

a species of butterfly discovered in Australia

New mutation in a population can:

introduce new genetic variation

a random change in allele frequencies in a population

the selection of traits that increase survival

the transfer of genetic material from one population to another

Statistics help explain evolution by:

providing evidence of genetic changes in populations over time

proving that all species remain unchanged

A modern example of natural selection is:

The development of antibiotic resistance in bacteria

The use of solar panels for energy

What is the scientific theory of evolution backed by?

extensive evidence from fossils, genetics, and observable phenomena

In natural selection, those with advantageous traits are more likely to? ________

survive and reproduce, spreading those traits.

What does genetic variation arise from? ________

mutations and sexual reproduction

When environmental conditions change, individuals with different genetic variations are? ________

more or less likely to survive and reproduce

always unaffected by the changes

What are Darwin’s finches? ________

finches with beaks suited to available food sources were more likely to survive

finches that are all identical in appearance

What can new mutation in a population do? ________

either improve or reduce its chances of survival in a changing environment

What can beneficial mutations lead to? ________

population that is better adapted to the changing environment and is more likely to survive

population that cannot adapt to any changes

What can harmful mutations lead to? ________

it may be eliminated from the population through natural selection

it may increase the organism's fitness

What is natural selection? ________

This is the process where individuals with traits better suited to their environment are more likely to survive and reproduce

This is the process where only the strongest individuals are chosen by humans

What is genetic drift? ________

random fluctuations in the frequency of alleles within a population, often due to chance events

the formation of new species through geographic isolation

What is gene flow? ________

the movement of genes between populations

How do statistics help explain evolution?

explaining and understanding evolution by providing methods to analyze and interpret biological data related to evolutionary processes

by preventing mutations from occurring in populations

What is a modern example of natural selection?

the evolution of antibiotic resistance in bacteria

the construction of skyscrapers

Differences or changes in characteristics within a species

Over time, the giraffe population may:

increase, decrease, or remain stable depending on environmental factors.

always increase regardless of conditions.

The following are the variations:

Different forms or versions of something

The favorable variation is:

The variation that increases an organism's chances of survival and reproduction.

The variation that has no effect on survival or reproduction.

Over time, the polar bear population may:

decrease due to loss of habitat

What may happen to the giraffe population over time?

Those with shorter necks will go extinct and those with longer necks will reproduce, creating a population of long neck giraffes

All giraffes will develop spots to blend in with trees.

Giraffes will start to fly to escape predators.

What may happen to the polar bear population over time?

Those with thin coats will go extinct and those with thicker coats will reproduce, creating a population of polar bears with thick coats

All polar bears will develop thin coats to adapt to warmer climates

Polar bears will stop reproducing entirely
