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 is the scientist who is most widely recognized for his contribution to evolutionary theory through the study of natural selection. Darwin's work provided the foundation for our understanding of how species evolve over time.
Why do scientists think that introns and exons contribute to evolutionary flexibility?
many biologist think that this organization of genes add evolutionary felixablity . Each Econ protein adds a different part of a protein by having introns and Exons fellas can occasionally shuffle exons between genes and make new ones .
What is the primary evolutionary unit in living organisms?
population is the primary evolutionary unit of any living organisms
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 a evolutionary biologist?
An evolutionary biologist studies how organisms have evolved over time through mechanisms like natural selection, genetic drift, and mutation. They investigate the processes that drive species diversity and adaptation, and how traits are passed down through generations. By studying the genetic changes that occur within populations, evolutionary biologists can understand the mechanisms behind the vast array of life forms on Earth.
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.
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.
What is a Repertoire of Invective?
a selection of insulting words or expressions
What is repertoire of invective?
a selection of insulting words or expressions
Who porposed the theory of evolution by natural selection?
English biologist Charles Darwin.
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.
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
What are other evolutionary mechanisms besides natural selection?
Other evolutionary mechanisms besides natural selection include genetic drift, gene flow, mutation, and sexual selection. Genetic drift is the random change in allele frequencies in a population. Gene flow refers to the transfer of genes between populations. Mutation introduces new genetic variation, and sexual selection drives evolutionary change through mate choice and competition for mates.
What evolutionary selection describes greater number at the extreme and few numbers at the center of distribution?
Disruptive selection, also known as diversifying selection.
