Question

What are the 3 conditions for natural selection?

Answer 1

Natural selection:

1. The adaptation and alteration of populations of living creatures are known as natural selection.
2. Natural selection is founded on three principles: most qualities are inherited (inheritance), more children are born than can survive(competition), and children with more desirable characteristics will survive and produce more offspring (variation).
3. Natural selection in operation can be seen in the evolution of giraffes' long necks.
4. Deer or antelope-like creatures with normal-length necks were the ancestors of modern giraffes.
5. Longer-necked giraffes, on the other hand, had an advantage over their shorter-necked counterparts.

The 3 conditions for natural selection are:

Variation:

1. The difference between two members of a species is referred to as variation.
2. Different skin colors, eyes, height, etc., are all examples of the variety.

Competition:

1. Competition is a biological interaction between organisms of the same or different species that happens when there is a limited supply compared to the demand for a shared resource.
2. There are two types of competition, namely intraspecific competition (between the species of the same group) and interspecific competition (between species of different groups).
3. Competition within and between species for resources is important in natural selection because it will help nature to know the fittest among the species.

Inheritance:

1. Inheritance refers to the transfer of genetic traits from a parent to their offspring.
2. Character inheritance happens only when a character is passed down through generations during reproduction.
