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?

There are enough resources for the birds.
the birds do not compete for resources

The population has not reached carrying compacity is correct on apex

What are two examples of species that evolved due to geographic isolation?
Galapagos finches (Darwin's finches)
How did Darwin's finches help him find his theory of evolution?
The finches on the Galapagos Islands helped him, as they gave him the basis of his idea of natural selection, which was the backbone of his Theory of Evolution. The birds beaks had altered slightly to enable them to eat the various foods available on their respective islands. This observation then prompted Darwin to extrapolate the data, and say that these small changes could eventually result in a fish turning into a reptile.
Which two forms of selection lead to two distinct phenotype?
if the pressure of natural selection is strong enough and lasts long enough , this situation can cause the single curve too split in two. i other words , selection creates two distinct phenotypes If the extremes of a trait are preferred to intermediate values, the ends of the spectrum live on as distinct phenotypes while the mid-range dies off. Darwin noted this in finch populations of the Galapagos, where islands with plants offering large seeds resulted in finches with large beaks, while small-seed islands had small-beaked finches. He believed they were of the same species, and had adapted to these extremes of beak size because of their environments.
Darwin began to formulate his concept of evolution by natural selection after what?
observation of many species and their geographical locations.
How do you regain the trust of zebra finches?
by giving them egg food
What body part of the Galapogus finches appears to been most mosified by natural selection?
The finches beak!!!
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 feature of Galapagos finches was important to Darwin in developing his theory of natural selection?
He noticed that there were different species of finches.
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
What are Darwin's finches a great example of?
Adaptive Radiation or Natural Selection (:
Research on Galapagos finches by Peter and Rosemary Grant showed type of natural selection is called what?
Directional Selection
How finches adapted different beak sizes on the galapagos islands?
natural selection
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?
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.

Why would a finch population that lives on an island have a higher rate of speciation that a finch population that lived in a large forest in north America?
A finch population on an island is more isolated than Êa finch population in a large forest. ÊThe gene pool of the island population would be more limited than the genetic possibilities of the finch population in the forest. ÊThe island finches would be more likely to pass on specialized genes than the forest finches. the island finches have more spatial isolation the island finches have more geographical isolation
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.
Darwin observed that some finches had larger beaks than other finches in the population on the Galpagos Islands What does this observation illustrate?
Variation
