Which scientists first presented the idea that over time traits that help individuals survive become more common within a population?
The concept that traits beneficial for survival become more common in a population over time was first articulated by Charles Darwin. He introduced this idea in his theory of natural selection, which he presented in his seminal work "On the Origin of Species" in 1859. Alongside Alfred Russel Wallace, who independently conceived similar ideas, Darwin's work laid the foundation for modern evolutionary Biology.

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.
Why is variation beneficial to a population that is undergoing change?
Yes, it is. If there is variation in a populations, and a sudden catastrophic event occurs, there is more of a chance that some of the individuals in the population will survive, and the population will not die out.
The mechanism of evolution by natural selection was presented by Darwin and?
it states that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to future generations. Over time, this process leads to the accumulation of beneficial traits in a population, driving the evolution of species.
What are the six points of Natural selection?
Variation exists within a population. Some variations are heritable. Organisms produce more offspring than can survive. Individuals with advantageous traits are more likely to survive and reproduce. Over generations, advantageous traits become more common in a population. This process leads to the adaptation of a population to its environment.
What are three factors that might kill off less well adapted individuals struggling to survive in a population?
Being able to catch prey, Avoid Being eaten, Adapting to their environment.

What percentage of newborn individuals in a population that can be expected to survive to a given age?
Surviorship
Which individuals are most likely to survive and reproduce in a population?
Those who are more adapt to there environment.
How can one determine the relative fitness of individuals within a population?
One can determine the relative fitness of individuals within a population by comparing their ability to survive and reproduce in their environment. Individuals with traits that help them survive and reproduce successfully are considered more fit than those with traits that hinder their survival and reproduction.
Why is a genetically diverse population the more likely to survive a change to the environment?
they are more likely to have individuals with an adaption

Which of the following was not part of Darwin's theory of natural selection?
A: More offspring are produced within a population of a species than can generally survive. B: More offspring are produced within a population of a species than can generally survive. C: Some individuals possess features that increase their probability to survive compared to individuals lacking these features. D: Some individuals possess features that increase their probability to survive compared to individuals lacking these features Individuals in a population of a species vary in many ways Individuals in a population of a species vary in many ways Changes in the environment cause beneficial mutations.
Why is genetic variation among individuals beneficial for a population's overall health and survival?
Genetic variation among individuals is beneficial for a population's overall health and survival because it increases the likelihood that some individuals will have traits that allow them to survive and reproduce in changing environments. This diversity helps the population adapt to new challenges, such as diseases or environmental changes, reducing the risk of extinction.
What is the sixteen letter word that describes the term that well adapted individuals successfully survive and reproduce than less adapted individuals do?
The term you are referring to is "natural selection." It is a key mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce, leading to the propagation of those traits in a population over time.
What will most likely happen if sudden changes in an environment occur and no individuals of a population are able to adapt to the changes?
If no individuals in a population are able to adapt to sudden changes in the environment, it is likely that the population will decline or face extinction. Without the ability to adapt to new conditions, the population may struggle to survive and reproduce, leading to a decrease in numbers and potentially the loss of the entire population.
What role does relative fitness play in determining the success of individuals within a population?
Relative fitness plays a crucial role in determining the success of individuals within a population by measuring how well an individual's traits help them survive and reproduce compared to others in the same population. Individuals with higher relative fitness are more likely to pass on their genes to the next generation, leading to evolutionary changes within the population over time.
