Why is DNA used as evidence in natural selection?
Mathematical analysis in genetics and comparative genomics can show scientists to what degree a particular genetic sequence resulted from selection pressures at a given time in the evolutionary history of the organism under consideration.
How does Evolutionary Trends affect Natural Selection?
Adaptation for stronger shells.
Which scientist contributed to evolutionary theory through the study of natural selection?
Charles Darwin contributed to the evolutionary theory through study of natural selection.
What evolutionary concept is indicated when the weakest members of a species is killed off?
Negative natural selection.
When Darwin published his theory of natural selection in 1859 he could not explain how traits were passed on to offspring what helped complete Darwin's theory of natural selection?
The discovery of discrete inheritance by Gregor Mendel. This genetic finding was combined with evolutionary findings to form the modern evolutionary synthesis that is still, with modification, the theory of evolution by natural selection today.
Who is Julian Hexley?
Sir Julian Huxley was an English evolutionary biologist. He was particularly involved in the field of eugenics and was a proponent of natural selection.
What is an evolutionary event in which population size is radically reduced?
Selection of a particular genotype threatened by hostile environment can radically reduce the population size of an organism.
What are other evolutionary mechanisms besides natural selection?
A very important mechanism of evolutionary change besides natural selection is geneticc drift.
What is the name of this type of evolutionary change?
Natural selection
Why is DNA used as evidence in natural selection?

Charles Darwin observed the resemblance between organisms on the Galápagos Islands and those on the nearest coast He hypothesized that the island organisms had evolved from the coastal organisms Wha?
Charles Darwin was the first evolutionary biologist who championed the theory of natural selection.
What is repertoire of invective?
a selection of insulting words or expressions
What is a Repertoire of Invective?
a selection of insulting words or expressions
Which of the following is the most powerful evolutionary force in large populations over time?
Only natural selection could be the answer here as natural selection is the main driver of adaptive change leading to evolutionary change and speciation in large populations.
The main force that results in evolutionary adaptation is?
Natural selection
Is artificial selection an agent of evolutionary change?
NO. Both artificial and natural selection are forms of Evolution in general. Both cause variation by selection within a particular population. The only difference is who is doing the selection, humans or nature.
Who porposed the theory of evolution by natural selection?
English biologist Charles Darwin.
