Five mechanisms
What is Gene Flow?
What is; the movement of alleles from one population to another.
What are branches that stop before the top of the Phylogenetic tree concidered?
What is; Extinct
What was Charles Darwin considered?
What is; The father of evolution
What is Natural Selection?
What is; The process through which individuals in a population have advantageous traits are more likely to survive and reproduce
Define Fitness
Ability to survive and to reproduce more offspring
When does non-random mating occur?
What is, When certain traits increase mating success
Organisms where the branches meet are...
What is; Ancestral
What was one of Charles Darwin's Observations?
What is; Species have common ancestors. Organisms have variations based on their environment. Some Variations provide advantages to surviving and reproducing.
Artificial Selection is when Humans breed organisms to produce desirable traits in the offspring of individuals in a population (Artificial Insemination) What are some examples of artificial selection?
What is; Dogs, Crops, Livestock,ect
Microevolution
The observable change in the alleles frequencies of a population over time
#ONEpopulation
A mutation is a random change in the DNA of a gene what are the different types of mutations in a DNA.
What is: Nondisjunction, Insertion, Deletion, Duplication, Frameshift, and Substitution.
The Node is Common Ancestors of what letter species?
What is; A,B,C,D,& E
Why was Charles Darwin considered the father of evolution?
What is; He was the one who proposed the concept of evolution
What are the four conditions of Natural Selection?
What is; Overpopulation, Variation, Adaptation, and Decent with Modification
Large-Scale evolution affecting changes in species across many populations or the entire species.
Macroevolution
The founder effect occurs after a small number of organisms colonize a new area. What is the Bottleneck Effect and what part of the five mechanisms does it come from?
What is; The Bottleneck Effect is an event that greatly reduces the size of a population; it comes from Genetic drift
Phylogenetic trees are like ______ _____ except that it extends for millions of years instead of a few generations, they're also used in a similar way as ________
What is; Family Tree and Pedigrees
What did species did Charles Darwin mainly study?
What is; Galapagos Finches, and Tortoises
Define Descent with Modification
What is; Individuals in the population with the advantageous trait survive and reproduce. Over Time, Individuals with advantageous trait make up most of the population.
What are the three different patterns of macroevolution
Divergent, diffrences
Parallel/Coevolution, Changes in eachother
Convergent, similar
Natural selection.
What is; A principle of evolution where organisms with better fitness tend to survive and reproduce more successfully.
On a Phylogenetic Tree where is the Oldest Common Ancestor located?
What is; At the Root
When did Darwin publish his findings and theory and what was the book called?
What is; He published his findings and theory of evolution by Natural selection in his book 'On the Origin of Species' in 1859
Overpopulation is
more offspring are born that can survive
Species that are closely related would have...
Very similar DNA sequences and proteins
