A small number of finches live in a protected bird area. They are given as much food as they need and have plenty of space. Why would natural selection not occur in this population?
Isaiah Bailey-gilyar...
There is no need for it to occur. Only if the environment changes and less food is found would there be a change. The environment selects the birds that do the best under the new conditions and the others will die.

Does natural selection work on preexisting variation in a population?
Natural selection does work on preexisting variations in a population. This is how the population was shaped to be the way that they currently are or were.
When part of a population becomes separated from the rest what often begins?
Natural selection
What are the different ways in which individuals with a particular trait may increase in a population?
different ways in which individuals with particular trait may increase are -if that particular trait provides them with some sort of support to undergo the circumstances they are found in, we can also call it natural selection -or due to any genetic drift, that is a natural calamity, also called a chance selection
How do populations benefit from individual adaptations?
because of natural selection
What is the source of new traits in a population?
New traits in a population can arise through mutations in the DNA of an organism. Mutations are changes in the genetic code that can result in new characteristics that may be passed on to offspring. These traits can then be subject to natural selection and other evolutionary mechanisms.
What body part of the Galapogos finches appears to have modified by natural selection?
The finches beaks were modified by natural selection. The beak size and shape varied from island to island.
What body part of the Galapogus finches appears to been most mosified by natural selection?
The finches beak!!!
What feature of Galapagos finches was important to Darwin in developing his theory of natural selection?
He noticed that there were different species of finches.
What are Darwin's finches a great example of?
Adaptive Radiation or Natural Selection (:
A small number of finches are removed randomly from the wild and placed in a protected bird area. they need and have plenty of space. why would natural selection not occur in this population?
The population has not reached carrying compacity is correct on apex
How finches adapted different beak sizes on the galapagos islands?
natural selection
Research on Galapagos finches by Peter and Rosemary Grant showed type of natural selection is called what?
Directional Selection
The different species of finches on the galapagos island are believed to have arisen as a result of natural selection acting on populations of finches that had experienced?
Evolution
Relate natural selection to the beak sizes of finches?
The numbers of birds with different beak shapes are changed by natural selection in response to the available food suply.
The similarities in the Galapagos finches implied?
The Galapagos finches only exist on the islands and inspired Charles Darwin. They implied that evolution occurs through natural selection.
Which 2 scientist demonstrated that natural selection is still at work in the evolution of finches?
Rosemary and Peter Grant.
Does natural selection work on preexisting variation in a population?
Natural selection does work on preexisting variations in a population. This is how the population was shaped to be the way that they currently are or were.
