evolution
The cold war is over; the domino theory is now irrelevant.
Vietnamization.
Charles Darwin was best known in the 19th century for his groundbreaking theory of evolution through natural selection, which he articulated in his seminal work, "On the Origin of Species," published in 1859. This theory proposed that species evolve over time through a process of variation and survival of the fittest. Darwin's ideas significantly challenged the prevailing views on creation and the immutability of species, laying the foundation for modern biology and influencing various fields beyond science. His work sparked widespread debate and changed the way humanity understands its place in the natural world.
The correct answer is Vietnamization ... the word Nixon used to describe gradually turning full responsibility of the defense of South Vietnam over to the South Vietnamese military forces while American forces were being withdrawn.
Alexander I became Emperor of Russia subscribing to the ideals of the French Revolution. Then he saw Napoleon take over the French Revolution and totally change it to a different direction. He saw his own attempts at reform sabotaged. He gradually gave up the effort.
Darwinism: it was discovered by Charles Darwin and so named.
The theory of punctuated equilibrium proposed by Stephen Jay Gould and Niles Eldredge suggests that genetic change can cause species to evolve rapidly in short bursts, with long periods of stability in between, rather than gradually over time. This theory challenges the traditional view of gradualism in evolution.

the theory of evolution
A gradual change in life-forms over time is organic evolution.
Darwin's theory of natural selection is referred to as gradualism because it proposes that evolutionary change happens slowly and gradually over long periods of time, through the accumulation of small, incremental variations in populations. This contrasts with other theories that propose sudden and abrupt changes in species.
Gradualism. This theory proposes that evolution occurs gradually over many generations through small, incremental changes in populations.
The theory of evolution proposes that species can change over time through processes like natural selection, genetic drift, and mutations. These mechanisms drive variation within populations, allowing those individuals with advantageous traits to survive and reproduce, resulting in changes in the species over successive generations.
The theory of evolution, proposed by Charles Darwin, states that changes in species occur gradually over long periods of time through the process of natural selection. This theory suggests that new species arise from the accumulation of small, incremental changes in traits that are advantageous for survival and reproduction.
Charles Darwin changed history with his theory of evolution. His theory of evolution suggested that species undergo small changes over time.
