Explain charles darwin’s idea of evolution by natural selection. chose two of the events or people that influenced him in developing his idea and describe how or what they did to influence his idea.

The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable traits, suitable (adapted) for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.

Some of the people that influenced Darwin are:

•Lamarck who first proposed  that humans evolved from a lower species through adaptations over time

•Malthus, economist who explained that population grows faster than food production could sustain. So, Darwin proposed that only individuals that have favorable adaptations would survive.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
