Variations within a population. Variations mean traits that only certain individuals have that give the individual a greater or lesser chance of reproducing.
A organism with traits that are suited to a certain environment have a better chance of surviving than organisms who's traits are not suited for the environment.
Genetic traits that give an advantage to an individual and can be passed on to offspring are called beneficial or adaptive traits. These traits increase an individual's chance of survival and reproductive success, allowing them to pass on these advantageous genes to their offspring. Examples include resistance to disease, increased intelligence, and improved physical traits for survival in a particular environment.
This is known as "natural selection." It is a key mechanism of evolution where organisms with advantageous traits for their environment have a better chance of surviving and passing on those traits to their offspring, leading to the gradual adaptation of populations to their specific environments.
Variation within a clade increases the likelihood that at least some individuals will have traits that are advantageous in the face of environmental change. This genetic diversity allows for some members of the clade to survive and reproduce, passing on their beneficial traits. As a result, clades with greater variation are more likely to adapt and survive in changing environments.
Differential reproduction
a greater chance to survive if the environmental conditions suddenly change.
I'm not sure what your question was, but I'm thinking you meant "WHY DO organisms with favourable traits have a better chance of surviving?". That's what I've answered below. Creatures which are better adapted for their immediate, local environment have a better chance of surviving because they are more able to overcome adverse situations specific to that environment. For example, if a creature eats a specific type of food and that food is only found at the top of tall bushes, a favourable trait would be being able to reach that food. Having these traits not only means that they have a better chance themselves of surviving, but it means that they have a better chance of living long enough to reproduce, thus passing on their genes. A prospective mate may recognise favourable traits and choose one mate over another so that her offspring may inherit those favourable traits and will have a better chance of survival.
the answer to this question is traits.
Selected Evolution takes place when one member of a specie has an property that is genetical and gives him an higher chance of surviving. This gives him an higher chance he wil get children, and his children will also have an higher chance of surviving. You get these things in like class 1 of the highschool. Feel ashamed.
This concept is known as natural selection, where organisms that possess advantageous traits for their environment have a higher likelihood of surviving, reproducing, and passing on those traits to their offspring. Over time, this process leads to the accumulation of beneficial traits in a population, increasing its overall fitness.
For natural selection to occur in a population, there must be variation in traits among individuals and differential survival and reproduction based on those traits. This means that some traits give individuals a better chance of surviving and reproducing in their environment than others, leading to changes in the population over time.
