In Darwin's Theory of Evolution over-reproduction refers to the fact that all organisms reproduce beyond the environment's ability to support them. true or false?

Asked in Biology
Organisms with traits well-suited to their environments survive and reproduce at a greater rate than less well adapted organisms in the same environment is called?
Asked in Science
What occurs when organisms that are better adapted to their environment survive and reproduce?
Asked in Zoology or Animal Biology, Evolution
What is the difference between the meanings of the terms evolution and natural selection?
Asked in Animal Life, Evolution
How does variation in species bring out an evolutionary change?
By natural selection. These organisms have variations that allow some to survive and reproduce better than other organisms. The ones that do reproduce better leave more copies of their genes in the populations gene pool. This is the definition of evolution; evolution is the change in allele frequency over time in a population of organisms.
Asked in Biology, Charles Darwin, Evolution
According to evolution evolution generally occurs when?
What is essnetial to evolution?
Genetic and morphological variation. Without variation in organisms there would only be the shifts of genetic drift and gene flow in organisms. When organusms are varied then one can be selected from the other by the environment and the organisms ability to reproduce against that environment. Then there is evolution.
Asked in Animal Life
The ability to reproduce results is an important part of any theory?
Asked in Natural Selection
What is part of theory of evolution by natural selection?
That all organisms vary. That there are more organisms born than the environment can support. That this leads to a struggle for existence in which the organisms whose variance causes then to survive and reproduce in greater numbers will leave more descendents that have this selfsame successful variation. Thus alleles change over time in populations of organisms and this is evolution.
