[Ans] What popular toy was originally intended to keep fragile equipment on a ship steady?

Step 1 : Introduction to the question "What popular toy was originally intended to keep fragile equipment on a ship steady?"

...A modern torpedo is a self-propelled weapon with an explosive warhead, launched above or below the water surface, propelled underwater towards a target, and designed to detonate either on contact with its target or in proximity to it.

Historically, it was called an automotive, automobile, locomotive or fish torpedo; colloquially called a fish. The term torpedo was originally employed for a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate an underwater self-propelled weapon.

[Ans] What was the name of the ship in which Charles Darwin, the naturalist, sailed around the world?

Step 1 : Introduction to the question "What was the name of the ship in which Charles Darwin, the naturalist, sailed around the world?"

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s, the scientific community and much of the general public had accepted evolution as a fact. However, many favoured competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.
