What is the difference between evolution and convergent evolution?
Evolution is the general theory itself, by which organisms change and adapt over time. Convergent evolution is a specific proces in which similar traits appear in unrelated organisms. For example, insects and birds both have wings but the two evolved independent of each other. That's convergent evolution.
What evidence do scientists use to prove that evolution has occurred?
Simple example. You know hair color is under genetic control. Two types, blond ( which is recessive ) and brown ( which is dominant ) exist in our population. These two alleles are in a 75% to a 25% frequency. ( dominant to recessive ) if that frequency changed to 60% to 40% you could say that evolution had taken place. Evolution is the change in allele frequency in a population of organisms over time. ( example very simplified ) PS Scientist do not prove things. They support their work with the evidence.
How does coevolution differ from evolution?
It doesn't. Co-evolution is simply a special case of evolution in which two or more species affect the direction of one another's evolution. The classic example is predator/prey interaction. All rabbits are variants and all fast rabbits vary among themselves also, with the faster ones surviving to reproduce ever faster rabbits. ( within physical limits and incrementally; think of how humans have shaved time off the mile run in the last 50 years ) This drives the evolution of faster, within limits, predators to chase these rabbits. Thus you get a arms race of coevolution in two interacting organisms.
What is the relationship between evolution and genetics?
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
What is co-evolution?
Two species evolving alongside one another, each one adapting according to selection pressures from the other one; a good example of coevolution is between a parasite and host species, and between predator and prey. If a prey species develops a way to better escape a predator species, that predator species, in response, will have to develop a better way to capture the prey.

What is it called when two very different species evolve to look like each other?
Convergent evolution may be the words you seek. This often happens when different species have to adapt to a similar environment. An example would be the similar body shape, and the shape of appendages; of both fish and of marine mammals.
What is an example of co evolution in the tundra?
This is when one animal will evolve into two different species. Many animals and insects will do this in certain areas.
What is affect evolution?
The term coevolution (affect) is used to describe cases where two (or more) species reciprocally affect each other's evolution. So for example, an evolutionary change in the morphology of a plant, might affect the morphology of an herbivore that eats the plant, which in turn might affect the evolution of the plant, which might affect the evolution of the herbivore and so on.
What are the two most common contemporary planning techniques?
project management and scenarios planning
What is the plural of memorandum of understanding?
There are two acceptable plurals - memorandums of understanding and memoranda of understanding.
What is exhibit parallel and divergent and convergent evolution?
Parallel evolution: two (or more) species or genera that evolve in similar ways over time. Divergent evolution: two or more closely related species or genera that evolve to become quite different from one another. Convergent evolution: two or more unrelated and dissimilar species or genera that evolve to become similar to one another, for example penguins (birds that used to fly), dolphins (mammals that used to walk on land) and fish (animals that were always swimming)
What is an evolution game?
a game where your creature changes/evolves throughout the game, famous evolution games are, evolution the game of life, spore, dark-spore(coming soon) and also two free flash games, monster evolution and bug evolution (but the last two defiantly aren't as good).
Is there an Example of investigatory project title living things?
Investigatory projects are often aimed at understanding the interactions between living things. An example would be the study of symbioses in two different species.
A pattern of evolution that results when two unrelated species begin to appear similar because of environmental conditions is?
Analogous evolution. Convergent evolution.
What two people disproved evolution?
The Darwinian model of evolution by natural selection has not been disproved.
Why has evolution made whales look similar to fish?
It is called convergent evolution. When two different animals have to adapt to the same environment (both whales and fish have to adapt to marine environments) evolution will make them start to look similar, even though they will still retain fundamental differences. For example, whales are mammals, and fish are... fish
