Development of Evolutionary Thought Flashcards
Evolution is a linear process where organisms evolved into more complex ones
Fiction
All living organisms share a common ancestor
Fact
This interbreeds the members of the same species
Population
Two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
Allele
No. of copies of an allele, divided by the total no. of alleles for the same gene
Allele Frequency
Small, generation- by-generation changes to a population’s gene pool.
Microevolution
Large-scale evolutionary events; appearance of new species
Macroevolution
This examines a population’s gene pool.
Evolution
This implies Inheritance to changes in traits from generation to generation
Descent with modification
This is the entire collection of genes and alleles
Gene Pool
This have two different alleles in a gene
Heterozygous
This means having identical genes from both parents
Homozygous (Dominant or Recessive)
This person from 1830 stated that all changes are gradual
Lyell
These people stated that individuals are different and species arise through the process of natural selection.
Charles Darwin & Alfred Wallace
He believed that individuals in a species are identical and unchanging
Aristotle
He believed that new species came from existing species through environmental forces
Lamarck
“Species change as they spread from their OG location.” - ?, AD 1749
Buffon
What year and how long did Darwin set sail to the Galapagos Islands?
1831 for 5 years
This body part of the birds made Darwin think that it descended from a single ancestral type.
Finch
Natural selection drew inspiration from what?
Artificial selection (AKA Selective selection)
This is when a human chooses desired traits and allows only the individuals that best expresses those qualities to reproduce.
Artificial selection
This occurs when individuals with certain genotypes have greater reproductive success.
Natural selection
Inherited characteristics make individuals more likely to survive and reproduce
Natural selection / Unequal reproductive success
This is when individuals compete for limited resources for survival.
Struggle for existence
New species rise after characteristics of a population changes over many generations.
Descent with modification
