Thomas Malthus
What is the term for a feature that allows an organism to survive better in its environment?
adaptation
homologous structure
variation
vestigial structure
What do you call the organisms that breed with each other and produce fertile offspring in the natural environment?
gene pool
niche
population
species
What happens to the survival and reproduction of individuals that are well adapted to their environment?
better traits
fewer mutations
more offspring
stronger genes
According to Darwin’s theory of natural selection, What do organisms needed to possess to survive?
characteristics their parents acquired by use and disuse.
characteristics that plant and animal breeders’ value.
the greatest number of offspring.
variations best suited to environmental conditions.
Which is a major concept included in Lamarck’s theory of evolution?
Change is the result of survival of the fittest.
Body structures can change according to the actions of the organism.
Population size decreases the rate of evolution.
Artificial selection is the basis of evolution..
Which statement about the members of a population that live long enough to reproduce is consistent with the theory of natural selection?
They transmit characteristics acquired by use and disuse to their offspring.
They tend to produce fewer offspring than others in the population.
They are the ones that are best adapted to survive in their environment.
They will perpetuate unfavorable changes in the species.
In each generation, the wings of experimental fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. What idea is disprove based on the given observations?
inheritance of acquired characteristics
inheritance of natural variations
natural selection
survival of the fittest
According to Darwin’s Theory of natural selection, individuals who survive are the ones best adapted to their environment. What is the reason for the survival of species?
possession of adaptations developed through use
possession of inherited adaptations that maximize fitness
lack of competition within the species
choices made by plants and animal breeders
Which of the following statements does NOT support Charles Darwin Theory of Evolution?
Darwin observed variation within the finches of the Galapagos Islands.
Darwin proposed natural selection as the mechanism for species change over time.
Darwin used DNA evidence to support the process of Natural selection.
Darwin wrote the book Origin of Species by Natural Selection.
Why do modern scientists discredit Lamarck's theory of evolution?
It suggested that evolution happened according to a plan.
It suggested that changes come from what a species want or need.
It suggested that acquired characteristics do not have a genetic basis.
It believed that there was no extinction among species.
Which of the following phases best describes the results of natural selection?
the natural variation found in all populations
unrelated but similar species living in different locations
the changes in the acquired characteristics of a population
the struggle for existence undergone by all living things
Bacteria adapt more quickly than elephants to environmental changes. Which BEST explains this difference?
Bacteria reproduce more rapidly
Bacteria populations are more isolated.
Individual bacteria grow more steadily.
Individual bacteria have more genes
Several individuals in a population of green beetles acquire a mutation that makes them blue and toxic to their primary predatory bird species. What do you expect will happen to this population over time?
The poisonous ones have higher fitness, and natural selection will lead to more blue and toxic individuals and fewer green beetles over time.
The poisonous ones have higher fitness, and stabilizing selection will lead to the population of beetles to be compared of mainly blue and toxic individuals over time.
The poisonous ones have lower fitness, and natural selection will lead to the population of beetles to stay green
The poisonous ones have no survival advantage, and the population will be a mix of green and blue individuals over time
Some areas of a forest contain rich soil, while in other areas the soil is poor. Plants of a certain species grow taller in the rich soil than in the poor soil. The taller plants receive more sunlight and can produce more offspring than the shorter plants. If these offspring grow in rich soil, they are tall, but if they grow in poor soil, they are short. Which of the following statements best explains why this situation is not an example of evolution by natural selection?
The observed differences in plant height are not due to genetics.
The differences in soil conditions do not affect all plants equally.
The short plants and tall plants are not isolated enough from each other.
The short plants are not accumulating gene mutations as quickly as the tall plants.
The short plants are not accumulating gene mutations as quickly as the tall plants.
Organisms developed the necessary characteristics just to survive and to adapt
to the environment.
Body structures that are not utilized will disappear while those that are often used
will further develop
Only those organisms that are most adapted to their environment will survive and
will be able to pass their genes to the next generation
Organisms acquired characteristics that can be inherited by their offspring
Georges Curvier believed that the emergence and destruction of species happened
because of catastrophic events, and after that, new species evolved. Which theory was described?
Acquired Characteristics
Catastrophism
Natural Selection
Use and Disuse
How does the Use and Disuse theory help explain evolution?
The stronger organisms are going to survive and be able to reproduce.
Mutation helps organisms become fitter, stronger, and live longer than others.
The acquired characteristics of our ancestors were passed on to the next generation.
The parts of an organism that the organism uses most will become larger and more developed.
Which of the following describes evolution?
When there is a change in the characteristics and adaptive traits of
the organism from one generation to another
When there is a change in the characteristics and adaptive traits of
the organism from one generation to another
Natural catastrophe causes the disappearance of an organism
It happens because we were able to inherit the good traits from our ancestors.
The Theory of Inheritance of Acquired Characteristics hypothesized that it was possible to pass on the acquired characteristics of parents to the next generation. Who was the proponent of this theory?
Georges Curvier
Charles Darwin
Jean – Baptiste de Lamarck
Thomas Malthus
