Molecular evolution is the process of evolution at the scale of DNA, RNA, and proteins. Molecular evolution emerged as a scientific field in the 1960s as researchers from molecular biology, evolutionary biology and population genetics sought to understand recent discoveries on the structure and function of nucleic acids and protein. Some of the key topics that spurred development of the field have been the evolution of enzyme function, the use of nucleic acid divergence as a "molecular clock" to study species divergence, and the origin of non-functional or junk DNA. Recent advances in genomics, including whole-genome sequencing, high-throughput protein characterization, and bioinformatics have led to a dramatic increase in studies on the topic. In the 2000s, some of the active topics have been the role of gene duplication in the emergence of novel gene function, the extent of adaptive molecular evolution versus neutral drift, and the identification of molecular changes responsible for various human characteristics especially those pertaining to infection, disease, and cognition.

Principles of molecular evolution

Mutations are permanent, transmissible changes to the genetic material (usually DNA or RNA) of a cell. Mutations can be caused by copying errors in the genetic material during cell division and by exposure to radiation, chemicals, or viruses, or can occur deliberately under cellular control during the processes such as meiosis or hypermutation. Mutations are considered the driving force of evolution, where less favorable (or deleterious) mutations are removed from the gene pool by natural selection, while more favorable (or beneficial) ones tend to accumulate. Neutral mutations do not affect the organism's chances of survival in its natural environment and can accumulate over time, which might result in what is known as punctuated equilibrium; the modern interpretation of classic evolutionary theory.

  • well if life evolved naturally, why do some people think that life couldn't start naturally also? i mean do we need to have a god/gods behind everything we don't fully understand? that show how ignorant some people are. lol

  • @steveb0503 Sadly evidence and rationality rarely persuades religious ignorance. Darwin proved it, Richard Dawkins wrote the selfish gene around 35 years ago which explains evolution from a gene's point of view. However creationist and other large portions of the religious community's will recite their usual mantra "It doesn't say that in my bible so it must be a lie" and completely ignore the facts and evidence thrown in their faces YET AGAIN! Honestly, how hard must we slap them to wake up?

  • @SFNightTripper Ummm nah faggot. I'm a beast so imma keep learned dis shiz so bak up DERP!!!

  • I want this video on my Vairy Touch II phone.

  • very interesting video thanks

  • great video thanks

  • Very enjoyable thank you

  • @Itstheclaw Get off these educational videos you simian sack of shit.

  • Apes have very different head, neck, shoulders, arms, wrists, hands, back, ribs, hips, knees, legs and feet because the controlling DNA is very different. The fossils found are always either human or ape. There is never anything inbetween.

    In real life, we are not related to apes.

  • .. does that also mean I will evolve into a yeast cell in about 1.5 billion years .. if so will I be allowed to drink my own wine .. or will that be incest?

  • Wow great presentation .. guess my genes are the same as the yeast .. except the yeast has some I dont ...

  • Good!! Very Infomative
