The process in which a species has changed over time is known as this.
What is evolution?
According to Charles Darwin the driving force of evolution.
What is natural selection?
What is Evolution?
This is a type of reproductive isolation in which the organisms breed at different times of the year.
Necessary for natural selection to occur, increases with gene flow, decreases with genetic drift
What is genetic variation?
Group of organisms that can reproduce and produce fertile offspring.
What are species?
These are the two main categories of reproductive isolation.
What are pre-zygotic and post-zygotic?
What is The Galapagos Islands?
This term refers to the availability of different traits and alleles within a population.
What is variation?
What is Molecular Biology?
If you start a population of mice that have approximately the same number of black, grey, and white mice, but at the end of two years there are mostly black mice left, what type of selection occurred?
What is Directional Selection?
Crickets vibrate their wings to attract a mate, wild other insects might have specific mating calls, therefore they will not breed. This is an example of this type of reproductive isolation.
What is behavioral?
This is the location where I eloped.
What is Ireland?
Natural Selection can only happen at this level of organization.
What is a population?
Organisms cannot breed due to a river blocking them.
What is geographic isolation?
This is how many years I have been teaching with YES Prep (including this year).
What is 8 years?
The concept that members of each species compete regularly for food, space, and other necessities is known as this.
What is the struggle for survival or competition?
Studying the distribution of organisms around the world to provide evidence of evolution.
What is biogeography?
During a tsunami, flooding causes about half of a population of hippos to be washed downstream and into the ocean. Hippos cannot swim; the ones washed away were simply in deeper water and couldn't get back to shore. This is an example of....
What is Bottleneck Effect? (Genetic Drift)
A horse and a donkey can have offspring, but the offspring are sterile.
This is the longest bone in the human body.
What is the femur?
Rafflesia flowers producing a smell to attract flies is an example of what?
What is adaptation?
An example of a vestigial structure.
Tailbone, ear muscles, wisdom teeth, appendix ....
List 3 evidences of Evolution
biogeography, comparative anatomy, comparative embryology, vestigial structures, homologous structures, fossil record, molecular biology, direct observation...
The biological definition of a species.
Published in 1859, Charles Darwin’s book _________ changed biology forever.
What is "The ORIGIN OF THE SPECIES"
The ability of an individual to survive and reproduce is known as this.Many of our household pets and produce that we consume are produced by this.
What is fitness?
The strongest and most factual evidence that scientists use for evidence of evolution.
What is molecular biology or DNA?
Natural Selection requires variation between individuals. It can increase genetic variation between individuals in a population.
What is a mutation?
This type of reproductive isolation is when the organisms will mate, but the offspring will die shortly after birth.
What is reduced hybrid viability?
