Evolution

I presume you mean the fossil primate, Lucy. Lucy provides evidence that hominids walked upright before developing a large brain; the fossil has a "modern" pelvis but a small brain - if you saw the animal alive, you might think it is a rather odd looking ape - appearing like a chimp but walking upright. The fossil concerns the evolution of modern man.

It shows how organisms change slowly overtime.

For example, examination of the inner ear bones of whales show how it changed from being able to hear well on land to being able to hear well in water as it evolved from a land mammal to a mammal that lived both on land and in the water, to one that only lives in the water.

This shows support of natural selection because it would be advantageous for an animal who was spending more and more time in the water to have hearing adapted to hearing in the water.

Answer 1

Two broad processes that make evolution possible are 1 : directional forces including mutation , migration and selection and 2: nondirectional forces that include random genetic drift , bottleneck effect , founders effect ,and chance variations .


Answer 2

Evolution is most commonly described as a combination of reproductive variation and differential reproductive success.

Reproductive variation in itself is a "non-directional" phenomenon, that produces mostly random variations. Differential reproductive success (or: natural selection) is a "directional" phenomenon, that basically acts as a mechanism limiting the set of "directions" produced by random variation.

Others claim that the state devoloped naturally and gradually out of early family. They hold that the primitive family, of which the fatheras the head of the family and thus the "government", was the first stage in human political devolpment. Over countless years the original family became a network of closely related fam8ilies- a clan. In time the clan became a tribe. When the tribe first turned to settled agriculture- when it gave up its nomadic ways and first tied itself to the land- the state was born.

Transgenic organisms could be used to make a new type of protein. For example, give a bacteria a new gene. The bacteria can then make the protein coded by the new gene. The protein may end being something such as human insulin or some other protein the bacteria don't normally produce.

The process of growth and change over time in an organism is called development. It involves a series of stages that involve cellular differentiation, growth, and functional maturation to reach the organism's full potential. Development is a tightly regulated process influenced by both genetic and environmental factors.

If you selectively breed two animals with a recessive trait, they will pass on that trait to their offspring. A recessive allele must appear twice in a genotype to appear physically. I hope I answered your question.

The genetic traits, both physical and behavioral, that the individual possesses on his personal genome.

That is called "Gradualism" (the alternate being "Punctuated Equilibrium").

Means a species always has that potential to breed, one with another. Still, different populations of that species may be too geographically divided to actually interbreed.

it's where a Pokemon has to have a certain item needs a certain move,needs traded, or has to get to certain lv.(level) to change into a similar form.Some Pokemon can evolve more than once(example: turtwig evolves into grotle and grotle evolves into torrterra)but some Pokemon can't evolve(example:groudon,dialga,and ditto)you can stop an evolution by pressing B while they evolve.Hope I helped:):):):):):)

There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.

The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.

The animal who doesn't adapt will die..that means the animal who was strong enough to handle it's environment breeds with another animal that was strong enough to handle it's environment. That results in offspring with the same strong qualities and it continues evermore.

Several scenarios are possible but only a few are likely

1. humanity destroys the evironment or itself and becomes extinct, the world will eventually recover and become a lush world again with the possibility of another intelligent race evolving.

2. humanity transforms the world in a grey city or a neo-city-complete with life growing on roofs and in special buildings. the possiblilty of space travel/colonization is possible but irrevelant.

3. the internet will eventually become capable of reproducing and reparing itself and given enough processing power and information it will become self-aware and a A.I. god will be born. People will still be around to provide the raw info input needed as the A.I cannot create new data but can use data. What the A.I. god does is anyone's guess.

4. humanity or some other force of nature will upset the amount of light the earth receives and will send the world into a frozen wasteland or a superheated furnace.

(ex: we paint the poles black for some reason, something changes the clarity of the air, a sea dries up and leaves only a white salt bed reflecting alot of sunlight)

5.humanity break some quantum law , creates a tear in the fabric of reality, tap into so infinite energe source but but cannot control it and all matter is destroyed or changed.

6. a black hole swallows the earth, interesting the earth just as well may stay the same as no one knows whats really in a black hole.

7. an object or human explosion strikes the earth with enough force to render it a collection of rocks flying through space.

8. a gas cloud (hydrongen) pass throught the solar system and strips the atmosphere from the earth, rendering it a lifeless piece of rock.

9. a massive burst of radiation from a supernova or other galatic event kills all life on earth and renders it lifeness until life evolves again. (or god creates everything if your religious)

10. a universal constant is broken or changed (the one concerning gravity and objects far from each other is already being stretched ) and therefore nothing exists or time will simply stop.

11. the universe expands much faster and as it expands, there will be less energy(lots of quantum science trust me) therefore we will all die out. but scientists also found that there's a way to make computers run with a set amount of energy forever, you just don't discard info or receive new info. So we'll all be cyborgs reliving the past over and over and over and over ...

12. society gets to a point where humanity is all knowing, with no reason to live as we'll know everything. We will either all commit suicide and leave a ghost planet for someone to find(very cool) or simply reduce our intelligence and technology and learn everything over again.

The Darwinian theory of survival of the fittest derived from his observations of Galapagos turtles. The turtles had to reach up high to find food in shrubbery, so the only ones that "survived" would be those that had longer necks. Over time the gene of long necks was passed on because all those turtles that had long necks had more of a chance of survival because they could reach more source of food. The organisms that were more fit for the environment survived. This also applies to: speed, mannerisms, length of wings, and ability to swim, plus many many others.

Habitat Stability.

Generally, mutation.

Charles Darwin and Alfred Russel Wallace proposed the theory called Natural Selection. This theory explained evolution.

Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.

Natural Selection

There must be genetic variation in the population

The system must not be in hardy-weinberg equilibrium.

resources must be limited in the ecosystem
