What did Darwin's theory of evolution provide that earler theories of evolution had not?
Darwin was by no means the first person to come up with a theory of evolution. However, he was the first person provide a mechanism by which evolution could occur. He called this natural selection and is essentially the way in which individuals with characterisitcs that better suit their environment survive and ones which don't die out. Therefore, eventually the whole species will possess these advantageous characteristics and evolution will have occured.
True or false Mutations can increase the variations in a species 'traits?
Mutations are important for evolution because they provide the variability whereupon natural selection acts.true last answered by zaporia
What type of natural selection causes no change in the population?
If a population exists in an environment that changes very little, then natural selection may not provide any pressure to change. However, even under these conditions genetic driftoccurs, introducing random change within the parameters set by natural selection.
How does camouflage provide evidence of Evolution?
Camouflage in itself doesn't provide evidence for evolution. However, seen in a large number of species living under varying circumstances, the range of types of camouflage and how they match their environments gives a big clue as to how evolution works.
Which cell provide non specific cellular disease resistance mechanism?
macrophages
What did Darwin's publication provide for the scientific community that had been lacking in previously published works about evolution?
As you said, previously published works were well acquainted with the process of evolution, but Darwin gave evolution a mechanism of action through his theory of evolution by natural selection in his 1859 publication.Natural selection is the nonrandom survival and reproductive success of randomly varying organisms.
What is mutation and how is it related to evolution?
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.

Why should people believe in evolution?
People should not " believe in " evolution but accept that evolution, the change in allele frequency over time in a population of organisms, is fact. The also need to consider the theory of evolution by natural selection, which explains much about evolution, as one of the most well supported explanatory theories in science. Then they would, if they are intellectually honest, come to accept not only the fact of evolution but the theory of evolution by natural selection. " Believe in " is a term one uses when one can provide no supporting evidence for one's concepts and this does not include evolution and the theory of evolution by natural selection.

What does evolution provide the raw materials for?
Selection by death.
How many people have died since evolution?
It is difficult to provide an exact number as the concept of evolution spans millions of years. Over the course of human evolution, many individuals have passed away, leading to the continued process of genetic variation and natural selection.

What provides the direction evolution takes?
The direction evolution takes is primarily determined by natural selection. This process favors traits that enhance an organism's survival and reproductive success, causing those traits to become more common in subsequent generations. Additionally, environmental factors play a role in shaping evolution by exerting selective pressures that favor certain adaptations over others.
Natural processes such as speciation and gradualism provide the genetic basis for what?
evolution
Natural processes such a speciation and gradualism provide the gentic basis for?
evolution
Mutations are important for evolution because they .?
Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.
