What is a characteristic that improves a individuals ability to survive and reproduce in a particular environment?
having genetic variation among most of its members
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
How does variation within a clade affect clade's chance of surviving environmental change?
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.
Natural selection will never favor those members of a population that have an extreme variation of a trait?
Natural selection can favor extreme variations of traits if they provide a survival advantage. For example, in a changing environment, individuals with extreme traits may be better suited to survive and reproduce. However, extreme traits can also come with disadvantages that may make individuals less likely to survive and reproduce.
How does variation ensure that a species to survive?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
Why is genetic variation importmant?
Because it yields variation of characteristics within the population, allowing for the most fit individuals (those who can best survive and reproduce) to prosper.

How can variation lead to survival in the changing environment?
The survival of a species relies on at least some individuals producing offspring. The organisms best adapted to their environment are the most likely to produce offspring. These are the organisms that have favorable characteristics, enhancing their ability to survive and reproduce.Their offspring will inherit these favorable characteristics. Over several generations, individuals with favorable characteristics will become the most common. In contrast, those with less favorable characteristics will be more likely to die before they get a chance to reproduce and so will become less common.For clear: We can say that favorable characteristics are ‘selected’. Variation in a species is particularly important if environmental conditions change. Some individuals will have characteristics that are favorable, allowing the species to survive the change.
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do?
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals is called natural selection. This is part of Darwin's theory.
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
What are four requirements for natural selection?
Natural selection occurs when four conditions are met: 1. There is variation among individuals. 2. That variation is at least partially heritable. 3. That variation is linked to differential reproductive success. 4. More individuals are born than can survive and reproduce.
What do better adapted individuals do?
Survive and reproduce.
What is the process by which organisms with favorable genes are more likely to survive and reproduce?
natural selection
How does variation within a species increases its chance to survive when the environment changes?
Variation within a species creates a diverse gene pool, allowing some individuals to possess traits that are better suited for the new environment. This increases the likelihood that at least some individuals will survive and reproduce. Over time, these advantageous traits can become more prevalent in the population through natural selection.
Survival of the fittest is the theme for natural selection?
"Survival of the fittest" is a term associated with natural selection, where individuals with favorable traits are more likely to survive and pass on their genes to the next generation, while those with less favorable traits may not survive or reproduce as successfully. This process leads to the gradual adaptation of species to their environment over time.
How does variation within a clade affect clade's chance of surviving environmental change?
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.
What scientists argued that variation among individuals allow evolution to occur?
Charles Darwin and Alfred Russel Wallace argued that variation among individuals is crucial for natural selection to act upon, driving the process of evolution. They proposed that individuals with advantageous variations are more likely to survive and reproduce, passing on those beneficial traits to subsequent generations.
