Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
How does the geological time influence the theory of evolution?
Geological " deep " time gives ample time for evolutionary processes to occur.
4 arguments for evolution?
No arguments; evidence. 1. The biochemical and genetic relatedness of all organisms on earth. 2. Biogeography. The distribution of organisms best explained by evolution. 3. Homology. The bones in your arm match almost bone for bone the bones in your dogs forelimb. ( save for structural modifications ) 4. The age of the earth and the processes that took place over deep time. Well supported from many disiplines.
What are the steps are involved in the formation of life on earth include ideas about chemical evolution and biological evolution?
The formation of life on earth has little to do with evolutionary sciences, which deal how lifechanges, not how it begins. The formation of life has as little to do, specifically, with evolution as it does with cell theory, or biogeography, or diet of organisms, or photosynthesis... it's a prerequisite for these processes.
The evolution of what biochemical processes changed the physical nature of the earth in such a way that most original life forms had to adapt radically or become extinct?
photosynthesis
What processes led to the evolution of multicellular organisms?
cell differentiation
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
How much natural selection leads to evolution?
All natural selection results in evolution. But natural selection is not necessarily the only mechanism leading to evolution. There are processes at work on a molecular level, such as intragenomic conflict-type processes, that also result in differential reproductive success, but aren't exactly related to the kind of processes Darwin first described.
What principles is not part of Darwin's original theory of evolution by natural selection?
Random processes are not part of the theory of evolution by natural selection.
What are the four processes that lead to evolution?
Mutation, Natural Selection, Migration, and Genetic Drift.
How does geologic and organic evolution compare?
There isn't really such a thing as "geologic evolution". Geology describes processes by which geological features may form or alter, but these are not in any way even remotely similar to the processes by which lifeforms develop over time. The changes wrought by geological processes can be (summarily) described in terms of mechanical forces acting on a single body of mixed composition; the processes involved in evolution require populations of self-replicating organisms. So really, they don't compare. At all.
What is naturalistic evolution?
Theistic evolution is the idea that God intervenes to guide the course of evolution. Naturalistic evolution makes no mention of God. Naturalistic evolution is the idea that evolution is a normal result of natural processeses. Naturalistic evolution is compatible with both atheism, and compatible with the idea of a God that can set in motion self-sufficient processes that work without any need for ongoing intervention.
What is the definition of biochemical similarities?
A generalization of the concept of molecular evolution is the observation that the basic biochemical processes of all organisms are very similar, despite the apparently arbitrary nature of many of these processes
Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
How does scientific evidence support the theory of geologic evolution?
I am a geologist and I know of no theory of "geologic evolution". "Evolution" as defined by Darwin describes the origin of species based on the survival of the fittest. This certainly can not be applied to geological processes, although life is integral to geology.
What is the ISBN of The Theory of Evolution?
The ISBN of The Theory of Evolution is 0-14-020433-4.
