What scientist did Darwin co-author a paper on natural selection with?
Wallace
What is the mechanism driving evolution according to Darwin's theory?
Natural Selection
What is one of the key aspects of Darwin's theory of evolution?
Descent with Modification
What did Darwin contribute significantly to the development of his theory during his voyage on HMS Beagle?
Made numerous observations and collected specimens
What did Darwin's theory of evolution propose about the diversity of life?
The diversity of life is the result of gradual modifications over vast periods
What did Charles Darwin begin developing in 1838?
His ideas on evolution through natural selection
What did Alfred Russel Wallace independently formulate a theory of?
Natural selection
Darwin visited the Galapagos Islands in a 5 year expedition aboard the HMS Beagle; he observed 13 varieties of finches and noted variation in traits such as their beaks (birds who ate larger seeds tended to have larger beaks, those that ate smaller seeds had smaller beaks), etc...
True
Darwin had been developing his ideas on natural selection, and then Alfred Wallace independently developed a similar theory of natural selection. The 2 co-published the theory in 1858.
True
Alfred Wallace is much better known for his work on natural selection compared to Darwin.
False
What was the name of Darwin's 2nd book:
The descent of man and Selection in Relation to Sex
What did Kimura propose about the majority of genetic variation at the molecular level?
It is selectively neutral and evolves by random genetic drift
What concept did Kimura's work contribute to the development of?
Molecular clock concept
What did Kimura propose about the rate of molecular evolution according to his neutral theory?
It is relatively constant over time
What concepts did Kimura introduce in the field of molecular evolution?
Synonymous and nonsynonymous substitutions
What did Kimura challenge with his neutral theory of molecular evolution?
The prevailing view that most genetic changes were the result of natural selection
What did Kimura's neutral theory propose about the observed genetic diversity within and between populations?
It is due to neutral mutations that persist over time
According to Kimura's neutral theory, what is the main cause of the observed genetic diversity within and between populations?
Neutral mutations
What did Kimura's work emphasize the importance of within populations?
Genetic variation and molecular diversity
Which theory has remained a key framework in the field of population genetics and molecular biology despite facing critiques and debates?
Kimura's neutral theory
What is the molecular clock in evolutionary biology?
A concept that suggests regular base pair substitution rates over time
What did Motoo Kimura emphasize in his theory of molecular evolution?
Processes independent of natural selection causing genetic and phenotypic variation
What did Kimura's theory of molecular evolution propose about synonymous substitution rates?
They are clock-like and regular
What is one of the significant contributions of Kimura's theory to evolutionary biology?
Recognition of the molecular clock
What did Kimura's work enable in evolutionary biology?
Calibration of evolutionary timescales and events
Alfred Wallace proposed that speciation could occur due to:
Geographical barriers leading to isolated populations evolving independently
Alfred Wallace's contributions to science primarily laid the groundwork for understanding:
Evolution and biodiversity
Alfred Wallace's concept of speciation proposed that isolated populations could evolve independently due to:
Geographical barriers
Which statement about genetic drift is NOT true?
Genetic drift is more pronounced in large populations.
Which statement about homologous traits is NOT true?
Homologous traits are the result of convergent evolution.
Which statement about sexual selection is NOT true?
Sexual selection is solely determined by external physical traits.
Which statement about intrasexual selection is NOT true?
Intrasexual selection is driven competition for a specific mate
