Fossils are like the clues the police use to solve a crime.
Each one tells a story. Like clues to a crime, where the police don't have to find a print of every footstep taken by a subject or confirm every thing that he did, the clues paint a logical outline of all the events around the crime.
Like clues in a crime the police do not initially identify a person they want to pin the crime on and then seek to tie him to the event - they find a number of clues which identify potential subjects of interest. They then attempt to prove the relation of these suspects to the crime until the trail of evidence is strong and dependable. Usually multiple facts on the same evidence are considered - for a crime it might be fingerprints and video tape and eye witnesses, for fossils it could be carbon 14 and dendronchronology and geologic strata.
hard core
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
Molecular genetics
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
Fossil records, anatomical similarities among different species, and the observation of natural selection in action were some of the key pieces of evidence used to support the idea of evolution when it was first proposed.
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
Fossil evidence, such as transitional forms showing intermediate characteristics between species, and genetic evidence, like similarities in DNA sequences among related species, both support the occurrence of evolution.
Evolution of humans and bacteria plus some animals eg)primates.
DNA is used as evidence to support the theory of evolution by comparing the genetic similarities and differences between different species. By analyzing the DNA sequences of organisms, scientists can trace evolutionary relationships and determine how species have evolved over time. This genetic evidence provides strong support for the idea that all living things are related and have evolved from a common ancestor.
Evidence of past glaciations have nothing to do with evolution except to show that the Earth is much older than 10,000 years old.
The four pieces of evidence that support the theory of evolution are the fossil record showing transitional forms, homologous structures in different species indicating a common ancestor, genetic similarities between different species, and observable examples of natural selection in action.
