How do species evolve
Organism develop a trait and over their life and pass those to their offspring
Some organisms develop a trait that they see benefits other organisms
Some organism have beneficial traits which allow them to survive and pass traits to their offspring
Organisms that have weaker traits seek out and breed with those
The primary difference natural and artificial selection is
In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).
In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).
Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.
They are different terms for the same concept.
If rubber bands suddenly replaced all other “food’ sources, what populations would be most successful?
Spoons and clips
Chopsticks and clips
Spoons and forks
Chopsticks and forks
Evidence show that all breeds of dog are the descendants of wolves. How did the huge variety of dogs arise in a few hundred years.
Genetics modification
Natural selection
Random chance
Selective breeding
Why did the population of grabbers that can reach one box reach a plateau and then drop off?
Their trait was not well suited to the environment, so the organisms were not “fit”
The organisms’ population never reached a sustainable size.
The other, larger, organism ate them
There is no logical reason for their decline
Why does the population with a 2 box reach steadily decline throughout the whole recording.
All other organism are out-competing the 2 box population
The 2 box individuals change into organisms that have a different reach.
The 4 box population eats the 2 box population.
The 2 box portion is being replaced in the total population with others
What is the (sometimes controversial) process of inserting a desired gene in the genome of an organism?
Gene splicing
Gene cloning
Genetic modification
Weapon Plus Program
What is the most common vector used to deliver gene theory.
Bacteria
Viruses
Fungi
Computers
What is meant by the phrase “individuals don’t evolve”?
Some organism don’t have the ability to evolve and all survive as they are.
Individuals adapt, the term evolution is only used for species
Evolution is a myth and is never observed at any level.
Traits become more or less common within a population as a result of success, rather than individuals acquiring new traits.
Which of these is not a benefit of artificial selection.
]Organism can become stronger
Breeding can be expensive
Farmers and breeder will have better business.
create new gene modification
