natural selection
th ability to survive and produce fertile offspring
Organisms that are constantly exposed to dangers, which can kill them in mass, have evolved to reproduce in high numbers so that enough of a species will survive and continue the species. Survival of the fittest and natural selection is a common practice among organisms that reproduce fast and in high numbers.
Natural Selection
Absolutely not... typically they will produce a multiple more than what will survive in order to maximize survivability... genetically speaking this increases the 'fitness' of the organism. Turtles and other reptiles will produce dozens of offspring only to have a small percentage survive, but reptiles take very little care of their young (the majority of the fates of the offspring are left up to chance and the strengths of individual offspring). Mammals will produce less (typically 1/2 of the number of nipples for feeding is the average birth number at one time). Mammals produce less because they take more care of their offspring and leave less to chance.Spider unfortunately (in this authors humble opinion), have WAY too many offspring! :)Have a great day,Synapse your fingers to the beat,Synaptophyllic
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals is called natural selection. This is part of Darwin's theory.
The answer of that qeustion is natural selection of which animals produce offspring.
Overproduction
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
Is the process in which something in a living things surrounds determines if it will or will not survive to have offspring
Fitness is a term that is used to measure the ability to survive and produce the most offspring.
It is populations which adapt. Alleles are passed on or not, offspring and individuals survive or not.
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
natural selection
Natural selection
yes
th ability to survive and produce fertile offspring
more offspring are produced than will survive
