Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time. The term "natural selection" was popularised by Charles Darwin who compared it with artificial selection, now more commonly referred to as selective breeding.

HELP I NEED A SCIENTIFIC MODEL AND PARAGHRAPH ABOUT ATOMIC THEROY WILL GIVE BRANLIEST AND POINTS
saveliy_v [14]

<h2>Atomic Theory:</h2><h2>Introduction</h2>

The atomic theory of Atoms Summed up is the idea that all matter is made of tiny particles that are imperceptible to the mortal eye; these particles are named Atoms

<h2>Paragraph 1:</h2>

John Dalton was the first to consider that all matter was made of tiny particles known as atoms. He invented the idea that matter is formed of atoms varying in weight.

<h2>Paragraph 2:</h2>

I created this model of the dissimilarities between three kinds of matter-- solids, liquids, and gases. The distance between atoms in each state tells us what type of matter we observe.

The Drawing is on the file

The End.
