What are five examples of evidence that support the theory of evolution?

Answer 1

1. Entomologist
2. Pharyngeal
3. Vertebrate relationship
4. Permian
5. Quaternary

Entomologists, Pharyngeal, and Permians are indirect and are Cambrian. Vertebrate relationships is cross-bred, and Quaterny's are humans.

Hope I helped (: I read it in my textbook ! Like my answer and check your phone screen , you'll see a new backround (; just like my answer please<3 it's right !

Answer 2

Evolutionary thought developed over decades, if not centuries. There are a number of evidences both in support and in opposition toward the theory of evolution. Some of the most popular evidences in support of Evolution are as follows:

• Natural Selection and Mutations -- In November of 1859, Charles Darwin published his famed book The Origin of Species, which is often considered the foundation of evolutionary Biology. In this, he discussed how populations adapt over long periods of time through natural selection, the belief that those animals with the stronger, more beneficial traits in a species outlive those with the less beneficial traits, thereby changing the overall traits of the species. Another trait, usually incorporated within natural selection, is the idea of spontaneous mutations within the genetic thread that cause random changes in a species that are sometimes beneficial to its survival.
• Speciation & Macroevolution-- Speciation is the process by which new biological species arise. This could be allopatric (when a species is split among two geological places), peripatric (small, isolated areas which prevent the species from exchanging genes with the main population), parapatric (the zones of two diverging populations are separate but do overlap), or sympatric (species diverge while inhabiting the same place). Macroevolution is the study of evolution that observes not what occurs in one species, but the changing of the state of the world as a whole.
• The fossil record-- The fossil record is a huge asset to those attempting to prove the evolutionary theory, as the fossil record provides visible, tangible evidence or the morphology of a species over time. However, very few complete specimens are ever found, and a great deal of speculation is required. Speculations, while an aid to study, is not conclusive.
• Strong connections between current species-- Most notably, the linkage existing between apes and humans. The DNA of both humans and apes contains 98% similarity between them.
• Theory of common decent-- The theory of common decent is the belief that all organisms on earth share the same ancestor and evolved into the myriad of species present today.

A more brief treatment: Five supporting observations for evolution are:

• Trackable changes in DNA
• Fossil evidence
• Observable modern evolution
• Demonstrable predictability
• Similar morphology in structures as species change

Answer 3

1. Fossil record: fossils in strata

2. Biochemistry: DNA & RNA

3. Comparative anatomy: homologous & analogous structures

4. Vestigial structures: organs that are no longer used

5. Embryology: study of embryonic development

Answer 4

The classification of lines of evidence into five different types is quite arbitrary. One could as easily distinguish two types, or five, or ten, depending on the criteria used. The difference between them would depend on the criteria chosen.

For instance: one might distinguish between evidence stemming from research in extant lifeforms on one hand, and from extinct lifeforms on the other. One might distinguish between genetic data and morphological data.
