What is the difference between natural selection and artificial selection?
Natural selection is when 'nature chooses' the organism with the favourable characteristics to survive. E.G. Giraffe's Long-necked giraffes are 'chosen by nature' because they have the favourable characteristic of being tall, which allows them to reach higher branches in higher trees. Whilst shorter-necked giraffes cant reach this food source and as the shorter trees run out of vegetation, the shorter-necked giraffes will end up dead.Artificial selection is when 'man-chooses' the organism that he wants because of their favorable characteristics,E.G Choosing the 'fat' cows to breed to produce more fat cows because they have more meat in them. This will in-turn affect the numbers of the 'skinner' cows with undesirable characteristics.Artificial selection is where man selects organisms with useful characteristics to him whereas natural selection is the process whereby nature selects the fittest organisms.A2. Some social insects such as ants employ aphids to grow fungi, it follows that the ants also have a part to play in Artificial Selection, in both the aphids and the fungi. So it is not just man.
Flying insects evolved by at least the?
Flying insects evolved by at least the Carboniferous period, around 350 million years ago. Some of the earliest flying insects were primitive forms such as dragonflies and mayflies, which developed wings for flight and became successful aerial species.
Are wings found in insects and chelicerates?
Yes, wings are found in insects, but not in chelicerates such as spiders and scorpions. Chelicerates have evolved a different body plan that does not include wings for flight.
What different kind of insects are killed by DDT?
For example lice and fleas.
What name Plant varieties pollinated by different insects?
Some plant varieties that are pollinated by different insects include sunflowers (pollinated by bees and butterflies), squash (pollinated by bees and beetles), and apple trees (pollinated by bees and flies). Each of these plants relies on different insect species for successful pollination.
What kind of insects live in artificial grass?
While it is tempting to say that artificial insects would live there, actually any kind of insect could nest in artificial grass. They can't eat it, but they could live there.
How could this be an advantage to the insects how could this trait have evolved through natural selection?
Well this could be an advantage to the insects because the insects can conceal with the color of the sticks. This trait could have evolved the through natural selection because its a chance of staying alive.
What process produced the two different types of beaks shown?
The process of natural selection produced the two different types of beaks shown. In this case, the environmental conditions likely favored different beak shapes for different tasks, such as cracking seeds or probing for insects, leading to the evolution of distinct beak shapes in the population.
What selection pressures may have fostered the evolution of a life cycle with such distinctive life stages?
many insects have a larval stage that is morphologically different from the adult and that feeds on different foods. what is the avantage of having different food sources for different stages of life cycle?
Are many insects have well-developed ears?
yes most of them but not all
What is the order of insects?
All insects are not in the same order, they are in the same class, Insecta, but below that they are different, I think there are 20-30 different orders of insects.
What is artificial breeding?
Artificial breeding is the act of manually inserting sperm into a female to get it pregnant. This is done with no contact between the male and female at all.
What kind of mouth does insects have?
Many, many different types of insects are determined by their different types of mouth.
What has the author Charles McKinley Wetzel written?
Charles McKinley Wetzel has written: 'Practical fly fishing' -- subject(s): Aquatic insects, Artificial Flies, Flies, Artificial, Fly casting
Why might the beak of the akialoa have developed in the way it has?
To dig through tree bark for insects.
Why didn't insects evolve?
They didn't evolve because they didn't need to. Natural selection roots out the weak genes which allow the strongest traits to survive. Evidently, as insects did not change, their traits and genes were already ideal for the environment, so they did not evolve.
How does cat flea is different from insects?
Insects can probably write English better.
