How helpful variations accumulate in a specie over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.
What trait is altered by variations in environment?
There is a long list, skin color, Diabetes, hair color, toenail length, lifespan, weight, to name a few.
What is the process by which of the best suited individuals can survive in their environment?
In science, this sometimes called the survival of the fittest or natural selection.If all individuals in a species are not exactly clones of each other but have small variations in the genes (traits), some will do better when the environment changes. These traits will be 'favored' over other traits.
What determines which traits in a population are favorable and which are unfavorable?
Traits in a population are determined to be favorable or unfavorable based on how they affect an individual's ability to survive and reproduce in a given environment. Favorable traits increase an individual's chances of survival and reproduction, while unfavorable traits decrease these chances. Natural selection acts on these traits, leading to the evolution of populations over time.
What two traits altered or changed by variations in environment?
If an animal is in a cold environment, it may grow thick skin or long hair. It may also produce other specialized organs for surviving in the cold weather. ex. a long nose to warm its mouth. Likewise, if an animal lives in a warm environment, then it may have very thin skin or short/no hair. Plus, it may be better adapted to keeping water.
What are genetic traits?
Genetic traits are variations of features passed on to offspring from there parents.
How do mutation or variations in organisms and selection cause evolution to happen?
Mutations or variations in organisms create genetic diversity, giving rise to individuals with different traits. Natural selection then acts on these traits, favoring those that provide a reproductive advantage in a particular environment. Over time, this process leads to the accumulation of advantageous traits in a population, resulting in evolutionary change.
What are four steps of nautral selcetion?
The four steps of natural selection are variation, competition, survival, and reproduction. First, individuals within a population exhibit variations in traits. Second, these variations lead to competition for resources, where some individuals are better suited to survive in their environment. Third, those with advantageous traits are more likely to survive and reproduce, passing these traits to the next generation. Over time, this process results in the population evolving to better adapt to its environment.
Where do variations in traits within a species originate from?
Variations in traits within a species originate from genetic mutations, environmental factors, and natural selection.
How does the environment cause variations in organisms?
Our genes decide what characteristics we inherit, but the environment can affect how these inherited characteristics develop, like a person could be tall but in their childhood have a poor diet which cause poor growth.
How do helpful variation accumulate in a species over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.
