What characteristics of your beak interfered with feeding success on the original island?
what is:
1.) size-beak is to small or big to pick up seeds
2.)How wide the beak opens
3.)weight of beak

what are 3 Traits that help individuals reproduce?
what is: attracting a mate, successfuly raise young,compete for nesting sites
In the Beaks of Finches Lab what did the selecting agent represent in the process of natural selection?
What is: size and Shape of the seeds
what did Darwin realized ?
what is:A flock of south American finches were stranded on the Galapagos
this serve a similar functions in different species but were not inherited from a common ancestor?
what is: Analongous Structures
when 2 or more species reproduce at different times?
what is: Temporal
what is survival of the fittest?
what is: "Fittest" is not necessarily the strongest species, but the survival of the species that can adapt to its environment
Name a trait other than beak characteristics that could contribute to the ability of a finch to compete successfully?
Answers could include: Shape of wings/color of feathers
size of body
eyes
size and shape of talons and claws
speed accuracy
what are the 4 conclusions that Darwin had?
what is:
1)variations in beaks
2)natural selection for most fit
3)offspring inherit successful traits
4)separate into different species
______ is a Shape reduction in the sizeof a population due to environmental events?
what is: Bottlenecking
what are the two lsolations we didn't wright in our notes?
what is: Reproduction and Ecological
Describe the Peppered Moth Evolution Drawing?
It started with an original population of some black and some Peppered moths. Then, smoke from the factories over the trees and the Peppered moths were mostly light making them easy to see and eat. When the smoke cleared, only the black Peppered moths survived.
In the speciation lab, there were groups of beetles that were split up. Suppose in 100 years the beetles from group 1 came back into contact with the beetles from group 2. Will they be able to reproduce with each other or will they be seperate species? Why?
If enough genetic differences and behavioral physical or ecological changes have occurred then they likely will not be able to successfully reproduce. In that case they would be considered separate species because reproductive isolation is a key factor. If they can still interbreed and produce fertile offspring then they would be considered the same species despite being separated for a long time.
