Who said "Natural selection is a force as immeasurably superior to the feeble efforts of man as the works of Nature are to those of art"

• Charles Darwin

• Gregor Mendel

• Aristoteles

• Alexander Fleming

What is Natural Selection?

• The process in which organisms that are not adapted to their environment tend to survive and transmit their characteristics to their descendants.

• The process in which humans that are adapted to their environment tend to survive and transmit their characteristics to their descendants.

• The process in which organisms that are adapted to their environment tend to survive and transmit their characteristics to their descendants.

• The process in which organisms that are adapted to their environment tend to die.

The species that we see around us today come from other species that existed in the past, they are the result of gradual modifications of their descendants; This process is known as ................

• Natural selection

• Evolution

• Variability

• Fossilization

The alterations that the environment causes to a living being are not hereditary, nor are those that it causes itself.

• True

• False

DNA is a short molecule that contains our unique genetic code

• True

• False

DNA it holds the instructions for making all the proteins in our bodies.

• True

• False

They are fragments or sequences of DNA that determine the characteristics of organisms.

• Chromosomes

• Allele

• Genes

• Amino acid

Mark the correct answer of natural selection:

• In a population, some individuals inherit traits that allow them to survive and reproduce.

• Individuals with the worst traits will have more descendeants than other members of the population.

• Since favorable traits are inherited and organisms that possess them leave more descendants, these traits will become very rare in the next generation.

• With the passing of generations, the population will be rejected to its environment

All living things share a common ancestor. we are also related to other mammals, to birds, to insects.

• True

• False

Fossils give an account of the evolutionary process: they document the extinction of species and the appearance of new ones

• True

• False
