  1. Lack of transitional fossils: Some argue that there is a lack of transitional fossils that show the gradual changes between different species, which is predicted by evolutionary theory.

  2. Complexity of living organisms: Critics question how complex structures like the human eye could have evolved through natural selection, arguing that they are too intricate to have developed gradually.

  3. Irreducible complexity: The concept of irreducible complexity posits that certain biological systems are too complex to have evolved in a step-by-step manner because they would not function without all their components present.

What are three major strengths of Darwin's theory of evolution by natural seletion?

Three major strengths of Darwin's theory of evolution by natural selection include its ability to explain the diversity of life on Earth through common ancestry, the adaptability of species to changing environments, and the predictive power of the theory in guiding scientific research and discoveries.


What are the three pieces of evidence for the theory of evolution by natural selection?

The three main pieces of evidence for the theory of evolution by natural selection are the fossil record showing transitional forms, comparative anatomy and embryology demonstrating similarities between different species, and molecular biology revealing genetic similarities indicating common ancestry.


What are 3 basic components to today's theory of evolution?

Three basic components of today's theory of evolution are genetic variation within a population, natural selection acting on this variation, and the inheritance of traits that confer a survival or reproductive advantage.


Who were the 2 main scientists that created the evolution theory?

Charles Darwin and Alfred Russel Wallace are the two main scientists credited with independently developing the theory of evolution by natural selection. Darwin's book "On the Origin of Species" published in 1859 is widely recognized as the cornerstone of modern evolutionary biology.


What are the 3 parts of Darwin's Theory of Evolution?

Darwin's Theory of Evolution consists of three main parts: variation, inheritance, and selection. Variation refers to differences in traits among individuals, inheritance involves passing on these traits to offspring, and selection entails the process by which certain traits become more common in a population due to their advantage in survival and reproduction.

What are the three theories of evolution?

In the scientific sense of the word 'theory' (ie. testable explanatory model), there is just the one theory of evolution: evolutionary theory, which incorporates the central theses of common descent and natural selection.


What are three types of evolution?

When we're discussing Darwin's evolutionary theory, we're discussing only one "type of" evolution: evolution by reproductive variation and natural selection. The term 'evolution' is also used in cosmology and Astronomy (eg. the evolution of the cosmos, the galaxy, or stellar evolution). But when used in this context, the term refers to something entirely different than what Darwin was talking about, and what evolutionary theory is about.
