What else can I help you with?
When did scientist believe chemical evolution occur?
Scientists believe that chemical evolution occurred around 3.5 billion years ago.
How does the evolution of gas occur in a chemical reaction give an example?
This is a sign of a chemical reaction.
Does evolution continue to occur in organisms today?
Absolutely. Evolution isn't an historical process; it is on-going as long as there is life.
How is chemical evolution and biological evolution the same?
Chemical evolution: the evolution of the elements (building blocks of matter) biological evolution: the small scale change in a population that can be passed from generation to generation Both of these are changes that occur to gradually create a new species or substance
How does biological evolution differ from chemical evolution?
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
Did evolution occur in the permian period?
Yes. Evolution ocurred in all geologic periods.
Where did evolution begin?
Evolution began with the first imperfectly replicating organic molecules. By which I mean the chemical precursors to life (something similar to RNA encased in a lipid bilayer). Evolution was around before the first things we would call 'life' by today's standards but was important in life beginning
How many natural element occur on the periodic table?
Today 94 elements (1 to 94) are considered natural chemical elements.
What are some draw backs of selective breeding?
You do not allow evolution to occur, for you are evolution in selective breeding.
How is variation related to evolution?
The more variation there is in a group of specimens, the more evolution can occur between them.
Why did evolution not occur in down syndrome?
Down Syndrome is a the addition of an extra chromosome and not really related to evolution. It is more of a genetic mutation that causes this event to occur.
