The scientific theory is evolution.
theory of evolution, theory of natural selection, as stated by Darwin.
evolution
Fossils give us a lot of information about species which used to exist on Earth but which are now extinct. With this information we can see in greater detail how species have evolved over time.
reproductive isolation
Over time, everything changes. Climates change, species evolve, ecological systems change, and so forth, and a species that was well adapted to a particular ecological niche may eventually find that its niche disappears or changes to the point at which that species is no longer adapted to it.
Living organisms slowly modify the evironment
Yes
Evolution is a change in species over time.
Darwin's four theories of evolution are: 1) Variation: individuals within a population have different traits. 2) Inheritance: these traits can be passed on to offspring. 3) Natural Selection: organisms with traits best suited to their environment are more likely to survive and reproduce. 4) Time: evolution occurs over long periods of time through the accumulation of small changes.
Species not always change over time such sponges :D
Because our society develops and further testing can disprove theories.
they can change over time
Evolution is the change in species over long periods of time.
A gradual change in life-forms over time is organic evolution.
Because society changes over time.
Adaptation is when a species is able to change over time to new changes in their environment.
When there are more convincing theories occur and proved experimentally, scientist will modify or change the current theories.
