Scientific Sequencing (Natural Selection)

Reorder the following steps for Natural Selection to occur.

• An organism is better able to survive due to an advantage.

• There are many organisms born. Some have different variations.

• One of the variations is favorable (has an advantage).

• If the organism survives they are more likely to reproduce and pass their advantageous trait on.

• This inherited trait will make the offspring more likely to have the advantageous trait and pass it on.

Reorder the following example of natural selection to show the sequence of the process.

•  When they pass on traits to their offspring, they are more likely to pass the large feet trait on to them.

• This will make it so that more of their offspring will survive and pass the large feet trait onto their offspring.

• There are many bunny rabbits born. Some with large feet and some with small feet (multiple variations).

• Because they escape more often, they are more likely to survive and reproduce.

• The rabbits with the larger feet have an advantage in the snow, where they don’t sink into the snow as easily; therefore, they escape from predators more often.

Reorder the following sentences to show the correct order of this example of natural selection.

• If the bacteria survives until the patient stops taking the antibiotic, it is more likely to reproduce.

• The bacteria that have a stronger resistance to the antibiotic, survives longer.

• There are many bacteria. Some of them are more resistent to antibiotics.

• When the bacteria reproduces (binary fission), it is more likely to pass this resistance on to the next generation.

Reorder the following example of natural selection to show the sequence of the process.

• The tuskless elephants are more likely to survive and reproduce.

• The population of elephants without tusks will increase because of the lack of a predator.

• Due to hunting of ivory, the male elephants with tusks are hunted.

• The male elephants without tusks have an advantageous trait.

• There are many male elephants born. Some have tusks, some do not (variations).

Reorder the following natural selection example about peppered moths.

• Peppered moths are born either light colored or dark colored.

• If they blend in better with the trees, they are more likely to survive.

• If they survive, they are more likely to reproduce.

• If the trees are dark, the dark moths have an advantage.

• If they reproduce, they are more likely to pass the advantageous trait on to their offspring.

Reorder the following examples of natural selection.

• Deer with smaller antlers or less points have an advantage and survive.

• Hunters select the deer with the larger horns (with more points).

• When they reproduce, they are likely to pass on the advantageous trait.

• Deer that survive, reproduce.

• There are male deers born with multiple versions of antlers.

Reorder the following natural selection examples.

• When a finch survives, it will live long enough to reproduce.

• Finches are born with many different variations of beaks.

• Finches born with shorter thicker beak depths have the advantage of breaking open hard, spiny fruits.

• When finches with favorable traits survive and reproduce, they will more likely pass this trait on to their offspring.

• If a finch is able to eat the fruit available, they will survive.
