Why is Darwin's theory of evolution considered to be a strong theory?

Answer 1

Darwin's three major contributions to evolutionary thought are;

1. There is genetic variation in all species

2. The variability is inherited - passed from parents to offspring

3. There are more offspring born than that survive to reproductive age

Answer 2

I only have two, sorry :P

• when his daughter died, he started questioning the existence of God.
• Wallace persuaded him to publish his book on his theory of evolution.

hope this helps!

Answer 3

It has been put to rigorous testing over 150 years and has stood that test. It best explains the data. It is supported by massive amounts of evidence from several disciplines. Actually, it is no longer just Darwin's theory but has been modified to some degree in that 150 years. For instance, Darwin was wrong about the hereditary mechanisms.

Answer 4

The mechanism that drives adaptive change in organisms that can lead to speciation.

In Darwin's own words.

The theory of evolution by means of natural selection.

Answer 5

Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations. This is called "microevolution."
But natural selection is also capable of much more. Given enough time and enough accumulated changes, natural selection can create entirely new species, known as
"macroevolution." It can turn dinosaurs into birds, amphibious mammals into whales and the ancestors of apes into humans.
Darwin also described a form of natural selection that depends on an organism's success at attracting a mate, a process known as sexual selection.

Other naturalists believed that all species were believed to remain much the same throughout time.
Darwin, however, noticed similarities among species all over the globe, along with variations based on specific locations, leading him to believe that they had gradually evolved from common ancestors.

He came to believe that species survived through a process called "natural selection," where species that successfully adapted to meet the changing requirements of their natural habitat thrived, while those that failed to evolve and reproduce died off.

Answer 6

what are the main components in Charle Darwin theory

Answer 7

1. How organisms are suited for life in their environments

2. The many shared characteristics of life.

3. The rich diversity of life.

Answer 8

diversity and distribution of species

uniformitarianism

Malthusian Law

Answer 9

1) Fitness

2)Fitness results from adaptation

3) adaptations are the result of natural selection and in the long run the evolution of a species

Answer 10

Evidence of evolution

Fossil record
