mechanisms of evolution Flashcards
process, biological population, inheritable characteristics, successive generations of the population, develops in a long period of time, adapt to the changes in their environment
evolution
sometimes called “theory of the inheritance of acquired characteristics” or soft inheritance, holds that an organism experiencing such a modification can transmit such a character to its offspring. Founded by Jean Baptiste Lamarck
Theory of Acquired Characteristics
parts of the organism that is regularly used will undergo hypertrophy and will be developed
theory of use and disuse
changes in the environment can arise to new needs, required for species’ survival
theory of need
organisms adapt to its environment and survive. Charles Darwin
Survival of the Fittest
species has descended and changed overtime
Descent with Modification
process through which populations of living organisms adapt and change
Natural Selection
identification of desirable traits by humans to perpetuate it to future generations
artificial selection
introduction of genetic material from one population of a species to another
gene flow
the frequency of a trait changes by chance randomly
genetic drift
genes are damaged or changed that alter the dna sequence
mutation
theory on evolution of organisms
theory of acquired characteristics, use and disuse, need, survival of the fittest, descent with modification, theory of evolution by natural selection, artificial selection
