Theory Of Natural Selection definitions

# Definition Sets
1 the idea that omly the organisms best suited for their environment will survive and reproduce 35 sets
2 the idea that only the organisms best suited for their environment will survive and reproduce 32 sets
3 evolutionary process by which favorable traits that are heritable become more common in successive generations of a population of reproducing organisms, and unfavorable traits that are heritable become less common 24 sets
4 natural selection of certain varieties, change in proportion of those varieties in the next generation (differential reproduction), extinction of poorly adapted forms 12 sets
5 a process that supposedly results in the survival of the organisms that are best suited for their environment 10 sets
6 heritable variation in traits influencing survival (ego reproduction) exists; therefore some individuals contribute more offspring to the next generation than others (differential survival and reproduction); heritable traits of these successful individuals become increasingly more abundant in the population over time; ergo avg. characteristics of the population change over time as the population evolves 10 sets
7 darwin 8 sets
8 the traits that make an organism more successful are passed on to offspring 8 sets
9 organisms that have certain favorable traits are better able to survive and reproduce successfully than organisms that lack these traits 7 sets
10 a theory that explains the process of evolution. it states that inherited characteristics that give an organism a reproductive or survival advantage are passed on more often to future generations than other inherited characteristics. 5 sets
11 the theory that states organisms best suited for their environment will survive and pass their favorable traits on to their offspring 5 sets
12 populations grow exponentially and exceed their resources. (malthus 17898) overpopulation results in competition and struggle for survival. in every population, variation among individuals leads to an unequal chance for survival and reproduction. 4 sets
13 better adapted organisms are more likely to survive and become the parents of the next generation. result: population changes over time; frequency of favorable traits increases in successive generations while less favorable traits become scarce or disappear. 4 sets
14 organisms better adapted to their environment will survive and reproduce-"survival of the fittest". 4 sets
15 unequal survival and reproduction that results from the presence or absense of particular traits that allow the organisms to better survive in it's environment 4 sets
16 the idea that genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future generations. 4 sets
17 a theory developed by darwin which states that the species that evolves is based on those that are best suited to survive. 4 sets
18 the idea that genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future genera- tions. 3 sets
19 the idea that the environment destroys organisms that are less able than others to live in the environment 3 sets
20 a process that supposedly that supposedly results in the survival if the organisms that are best suited for the environment 3 sets
21 nature selects the most advantageous variations -species evolve 3 sets
22 1. organisms adapt to their environment 2. those organisms best adapted will have a greater chance of surviving, reproducing and thereby passing their genes on to the next generation 3 sets
23 the idea that genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future generations 3 sets
24 in a species of genetically differing organisms, the organisms with the genes that enable them to survive better in the environment and thus reproduce more offspring than others will transmit more of their genes to the next generation 3 sets
25 "survival of the fittest" - overproduction leads to competition, variations and selections 3 sets
26 states that the environment may affect individual organisms in a population 3 sets

28 developed by darwin, theory that the species that are the strongest and best equipped for their ecosystem will survive and reproduce. 3 sets
29 postulated by charles darwin, this theory includes the idea that in any species the smart and strong survive and pass on their genes. it represented a major challenge to religious explanations of creation. 2 sets
30 the idea, originating with darwin, that genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future generations. 2 sets
31 based on darwin's idea that chance genetic variations producing adaptive reproductive and survival advantages will increasingly characterize a species over time. 2 sets
32 the idea, originating with darwin, that genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future generations 2 sets
33 the enviroment may cause certain characteristics to become domniant in a population by allowing organisms with the most suitable traits to survive long enough to reproduce 2 sets
34 genetic variation, over production of offspring, struggle for existence, different survival and reproduction 2 sets

37 genetically based characteristics that enhance an animal's ability to survive, and therefore reproduce, will be passed on to future generations. 2 sets
38 the idea that the environment destroys organisms that are less able than others to live in the environment 1. more young are produced than can remain alive; some will die 2. individuals in a species compete with each other for available resources 3. some individuals are better able to compete 4. the individuals with the best characteristics to obtain the resources they need will survive 5. those individuals that reproduce pass on their traits 6. only the organisms best suited to survive will be able to pass on their traits 2 sets
39 tenets of this theory include --populations tend to overpopulate --overpopulation results in competition and struggle for existence --in any population, there is variation and an unequal ability of individuals to survive and reproduce --only the best-fit individuals survive and pass traits to offspring --evolution occurs as advantageous traits accumulate in a population 2 sets
40 process that supposedly results in the survival of organisms that are best suited for their environment 2 sets
41 overproduction- species produce more offspring than the environment can support variation- species produce more offspring with characteristics that differ; different varieties exist selection- environment selects traits that make it easier for an organism to survive and reproduce adaptation- trait that improves survival will become more common; overtime, the amount of organisms with advantageous traits will increase 2 sets
42 predicts that over time, the number of individuals that carry advantageous traits will increase in a population) 2 sets
43 mutations create new traits. if a trait is beneficial, the better organism will reproduce and pass it off to its offspring. if not, the organism dies off. 2 sets
44 -produce excessive number of young to deal with dwindling natural resources -certain heritable variations allowed for some organisms to survive with limited resources 2 sets

77 1. variation= no 2 organisms are exactly alike 2. overpopulation=there are more organisms than the environment can support 3. competition=under some circumstances, there may not be enough resources, so they fight over them 4. selection="survival of the fittest"; the best-suited organism (in the environment) in the competition will win and live, the others will die 5. inheritance of the desired trait= organisms w/ the best traits will live to pass on their genes 1 set
