Darwin's theory of natural selection is often misinterpreted It is based on the need for survival in response to one's surroundings Which sentence best explains natural selection?
Natural selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully. Over time, this results in the evolution of traits that better suit the changing environment.
Which part pf Darwin's theory of evolution explores natural selection?
Darwin developed The theory of evolution by natural selection.So, to answer you question, all of it!You need to make a distinction between evolution, the change in allele frequency over time in a population of organisms, and natural selection, the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of evolution.
That evolution by natural selection is occurring in this cactus population?
To determine if evolution by natural selection is occurring in a cactus population, you would need to observe changes in the heritable traits of the cacti over time, caused by differences in survival and reproduction. This would indicate that certain traits are being favored, leading to a shift in the genetic makeup of the population.
In artificial selection humans provide the selective pressure for species to change and shape the evolution of various breeds What provides the selective pressure in natural selection?
The need for a change itself. For example, the need to migrate in order to keep up with food sources would bring an organism into another territory that their bodies might not be adjusted to. Rather than dying off, the "fittest" organism of that breed might mate with another "fit" organism, and after - guessing - 20 generations or so, genetic changes will have made that territory the most suitable environment for that organism.
Why did Darwin's theory of natural selection challenge the ideas of the church?
Answer 1Many churches of the time posited that god created all the organisms of earth at one time, so that no organism was related except to vary from it's created kind. Darwin showed that through the process of natural selection new species were constantly arising from related organisms.Answer 2Theism rationalizes its beliefs in deities by pointing to the organized nature of nature, claiming that such complexities could not have come about through unguided natural processes. Darwin, with his theory of natural selection, provided just that: an explanation for natural complexities in terms of unguided processes. Basically, while Darwin's theory does not claim that no gods are involved in nature, it did away with the need for any gods to explain the diversity of life.
Is descent with modification caused by natural selection?
No, it's the other way around: descent with modification is what you need for natural selection to happen.
Why does natural selection act on the phenotype and not the genotype?
in need helpl asap
What causes populations to complete?
Compete? The need to be a moron. Complete? The lack of natural selection.
What does Survival of the fittest and natural selection mean?
Survival of the fittest is a not quite accurate phrase for natural selection. Natural selection is, The non-random survival and reproductive success of randomly varying organisms.
What is the need for conservation of natural vegetation in India?
We need vegetation because it gives other animal a place to live. In order to protect the ecosystem of that place and also the gene pool for the survival of future generations
What are the factors that cause natural selection?
people, rats, and batsYou only need one - its called death.
What level does natural selection occur at?
natural selection occurs when animals need it
Why do evolutionary thinks use the word tinkering?
Because that is what evolution is, the tinkering process of natural selection working with what it has against the immediate environment. Evolution does not plan ahead and can not order parts to need, but must take what it has and adapt it to the time and place it is in. So, you are still a tetrapod, a four legged mammal, but you are bipedal due to the selective pressure on humans to stand erect. Natural selection, in the immediate environment, cobbled together an organisms that probably knuckle walked into an organism that walks erect in an obligatory manner.
Why are mutations and conjugation important for natural selection in prokaryotes?
Becauase they need to adapt to the new environment to enter the bodies
How is natural selection related to the concepts of niche?
by having different varieties in your body and how they both need something to survive.

How does this selection make you feel about the place of people in the cycle of life?
because animals need a place to live just like people
