The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

## What did Charles Darwin Research?

The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

## What does E mc2 calculate?

E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

## What are the two theories of relativity?

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.

## What is Einstein’s theory of general relativity?

Einstein’s 1915 general theory of relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. The scientist proposed that objects such as the sun and the Earth change this geometry.

## What kind of research did Darwin do that led to his theory of evolution?

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

## Where did E mc2 come from?

Bottom line: On September 27, 1905, Albert Einstein published “Does the Inertia of a Body Depend Upon Its Energy Content?” in the journal Annalen der Physik. In it, he described the interchangeable nature of mass and energy, or E=mc2.

## What are the six types of macroevolution?

There Are Six Important Patterns of Macroevolution:

• Mass Extinctions.
