How Groups of organisms change over time?
evolve
What events occured that allowed single celled organisms to evolve into more complex organisms at the end of the precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
Which kingdom did organisms evolve first?
Prokaryote organisms, such as blue algae, are believed to be the first organisms to have evolved through photosynthesis about 3 and a half billion years ago.
What does it mean when organisms evolve?
they change in ways or mutate in to a different form.
Explain why it is incorrect to say that individual organisms evolve?
It is not correct to say that individuals evolved because it is not possible for an individual to change drastically over their own timelife. Species have the faculty to evolve as a whole not as individual organisms.
Do organisms decide to evolve?
No
How many organism's might evolve?
all of the organisms can evolve.
What changes were necessary in earth's atmosphere to allow complex organisms to evolove?
During the few billion years following the appearance of cyanobacteria, oxygen became a major gas in Earth's atmosphere. The ozone layer in the stratosphere also began to develop, shielding Earth from ultraviolet rays. These major changes in the air allowed species of single-celled organisms to evolve into more complex organisms.
What process in Darwin book say what organisms evolve through?
Darwin said that organisms evolve through the process of natural selection.
Will cats continue to evolve?
Evolution is the change in allele frequency over time in a population of organisms. So, cats will continue to evolve. Organisms evolve, or go extinct. Speciation is another thing.
What organisms did humans start to evolve from?
autotrophs
Why is water necessary for organisms?
The water moistens the organisms.
What is the general rule about the complexity of organisms as they evolve?
The general rule about the complexity of organisms as they evolves is that it increases over time. Organisms start out very basic but can become very complex as they evolve over many generations.
How Groups of organisms change over time?
evolve
Do organisms evolve slowly over time and can two different organisms have a common ancestor?
Yes they evolve slowly over time and a panda and raccoon have common ancestors.
When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
The biological species concept assumes that organisms regularly?
evolve
