Changes in a species over long periods of time?
Changes over species over long periods of time is known as evolution.
Changes in species over long periods of time are called?
adaptations or evolution?
What is The process of forming new species by evolution from preexisting species?
Evolution.
What evolution of two or more species from one ancestral species?
Divergent evolution
Why does the presence of extinct and transitional forms in the record support the pattern component of the theory of evolution by natural selection?
supports hypothesis that species have changed over time.
What is a model of evolution in which short periods of drastic changes in species are separated by long periods of little or no change?
Punctuated equilibrium.
What is the process of becoming adapted to the environment?
a model of evolution in which short periods of drastic change in species are separated by long periods of little or no change
Contrast the hypothesis of punctuated equilibria with that of gradualism?
punctuated equilibria accounts for the gaps in the fossil record. Species evolve quickly during relatively short periods. Tiny changes in a species gradually add up to major changes over very long periods of time. Gradualism proposes that evolution occurs slowly but steadily. These periods of rapid change are separated by long periods of little or no change.
The hypothesis that the evolution of different species occurs?
natural selection
What do scientists call the change in species over long periods of time?
Evolution is the change in species over long periods of time.
Changes in a species over long periods of time?
Changes over species over long periods of time is known as evolution.
What was Lamarck's hypothesis regarding evolution?
That evolution occurs through the use and disuse of physical features by individual members of a species.
The hypothesis that species originate through a slow buildup of new adaptations is known as what?
Evolution
The hypothesis that the evolution of different species occur at a slow constant rate is called?
Gradualism.
The hypothesis that species originate through a slow buildup of new adaptation is known as?
Evolution
What do you call changes in a species over long periods of time?
It's Evolution
Changes in species over long periods of time are called?
adaptations or evolution?
