When samer was born, stimulation in his brain resulted in a massive overabundance of synapses. neurons that were seldom stimulated soon lost their synapses. this process is known as?

Synaptic pruning.
Synaptic pruning is the process of eliminating neurons and synapses that are not profitable for the well-function and efficiency of neuronal transmissions. Since the beginning of the brain development until the baby is born, and after, up to 2 years of age, new neurons and synapses are created in an exponential way. This pruning starts early from 2 years of old until 10 years of old or later.

Is there any answer choices?

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
