As shown in the question above, Darwin's work generated a map where the lines and forks created an image similar to a tree.
This "tree" linked species and places studied by Darwin. This connection was established by a common connection to all the species that Darwin studied. This connection was the common ancestor that a set of species shared and that was essential for the evolution of species to be understood.
Charles Darwin was an English naturalist that was born in 1809. He proposed theory of evolution after he carried out some experiments. He reduced that organisms arise and develop through natural selection which is a variation that help organisms to develop some characteristics which help them to survive and adapt to their environment.
The main motor contacts of a magnetic starter closed by
Electromagnetic solenoid. They operate
on current intensity, as motor current increases the solenoid's magnetic field
does as well. This lifts the solenoid piston upwards opening a set of contacts.
