What allows natural selection and evolution to occur for a tree?
differences in the characteristics of individual trees
How may natural selection be able to cause evolution to occur?
By selecting the variant organism most suited to the environment the alleles of the population then change in frequency over time and thus evolution occurs.
Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
What allows natural selection and evolution to occur?
the unequal ability of individuals to survive and reproduce
What is the most important force in shaping evolution?
Evolution has two key driving forces without which it would not occur, but with which it must occur: The first is reproductive variation: this basically asserts that each organism is slightly different from both its parents and its siblings. The second is differential reproductive success: this asserts that features that allow their bearers to reproduce more successfully than members of the same species with different features are likely to be present in a greater part of the population in coming generations. In other words: the key driving forces behind evolution are variation and selection.
What level does natural selection occur at?
natural selection occurs when animals need it
What allows natural selection and evolution to occur for a tree?
differences in the characteristics of individual trees
Does natural selection occur in the world today?
Yes, natural selection is always occurring.
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
What is the third step in natural selection?
There are really no steps in natural selection - just conditions required for it to occur.
How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
How long does it take for adaptations to occur with natural selection?
Individual animals do not adapt. Adaptation happens over generations within a species in a certain environment.
what causes natural selection to occur?
the presence of predators
How does natural selection produce adaptation's in a species?
the theory of natural selection is where "survival of the fittest" comes from. certain mutations occur in the birth of an organism that may be good or bad. in order to adapt, a species needs to mutate in a certain way in the next generation. this may take hundreds, thousands, or millions of years but eventually the optimal organism will emerge
What requires natural selection to occur in a population?
genetic variation
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What term is defined as natural change that occur in communities over time?
Natural selection
