Evolution 1
What better describes Evolution?
A) The gradual change of populations over time
B) The gradual change of individuals over time
What is A?
How is it possible that two completely different organisms can have similar body structures and anatomy?
If they have a common ancestor, they will likely be similar in some way
An inheritable change in characteristics within a population from one generation to the next?
What is evolution?
What type of beak would a finch have that would make it adapted to feed on nuts and seeds?
What is a crushing bill?
A random mutation in rock squirrels makes some squirrels have bigger cheek pouches to carry food than others. Would this squirrel likely be more or less likely to pass on genes?
What is more likely. This is a beneficial mutation.
A sudden environmental disaster changes the ecosystem that a population of snakes are living in. If none of the population is able to adapt, what will likely happen to the snakes?
What is extinction?
Can theory of evolution ever change and why or why not?
What is yes and when new evidence is discoverd?
What would the analysis of DNA from a badger and lion reveal?
What is there DNA sequences are similar?
What type of beak would a finch have that would make it adapted to feed on insects?
If an organism is extremely fit in one environment, does this mean it will be properly adapted to another environment? Why?
No, organisms are only "fit" in their unique environment
The forelimb bone structure of a whale, lion, and human are similar? What does this suggest?
What is they have a common ancestor?
How do DNA mutations produce an organism that could be the beginning of a new species?
What is when the mutation is beneficial?
How can genetic diversity be introduced to a population?
What is a DNA mutation?
What is used to classify organisms in a dichotomous key?
What are characteristics?
What trait allows a Juniper to survive in the desert?
What is drought tolerant?
These are structures found in organisms that have little or no current function, but are remnants of features that were useful in their ancestors—such as the human appendix or the pelvic bones in whales.
What are vestigial structures?
What is an environmental event that can trigger the development of a new species?
What is a predator, diet, climate, or location change?
The formation of new and distinct species in the course of evolution.
What is speciation?
What is an observation that could be made by looking at the skeleton of a modern day bird and the fossil of a dinosaur?
What is they are related?
Traits that are favored by the environment accumulate or time and will allow the favored organism to _____ and ______.
