Evolution happens when processes such as natural selection occurs resulting in certain characteristics becoming more common. The fossil record is a history of life documented by fossils and the remains and imprints of organisms from much earlier times. Over time changes have occurred in features of organisms living on the planet. One example of evidence from fossils is the transitional form of Pakicetids (an early ancestor to our modern whale) it had nostrils located at the front of its skull it has now evolved to the top of skull

There are four types of evolution, natural selection, genetic drift, mutations and gene flow. The two most relevant processes of evolutionary change is natural selection and genetic drift as these both have an important role in evolution.

Natural selection is where some organisms are more suited or adapted to there environment and therefor survive and reproduce longer.

Genetic drift is a change of an allele within a population over time, gene variation must occur randomly for genetic drift to occur.

DNA is they molecule which carries the genetic code for almost living thing Biogeography is the study of how species are distributed throughout the planet.

One example is how an isolated region like Australia seems to produce unique animals like marsupials that are clearly related to marsupials in South America, despite being thousands of miles away Gene therapy has and will impact human life massively in good ways and bad. Gene therapy is an experimental technique that uses genes to treat or prevent illnesses. This prosses is undergone by inserting a gene into the patients cells which can replace using drugs and other medicines. This can cost overwhelming amounts of money with the first year of a trial costing up to $750.000 and an additional $375.000 for any further treatments.

Ethically how can good and bad uses of gene therapy be known, who decides which attributes are considered a disability or a disorder or what is normal and not, and a very moral and significant question would be could the widespread use of gene therapy make society, which is already extremely opinionated against people who want to an be individual, less accepting of people who are different?

Germline gene therapy definition germline gene therapy is process of genetically modifying sperm or egg cells to create a new offspring

Germline gene therapy is controversial. While it could spare future generations in a family having a particular disorder, it might affect the development of a fetes in unexpected ways or have long-term side affects that are not yet known.

Because the people having the therapy are not yet born the ethical concern is they don’t have any choice in the decision.

The bad sides of Gene therapy and gene engineering is that it can lead to unknown side effects such as allergic reactions and toxicity. Genes which weren’t naturally there, and are artificially added can affect humans, animals or the patient/plant itself in negative ways. The impact envriomently with gene therapy raises both positive and negative implications. Organisms which are created by genetic engendering could cause an ecological disaster as we can not predict the changes that genetic engineered species would make on the environment. Releasing genetic engineered species and organisms has the possibility of upsetting the natural balance of the eco system.

The bad sides of Gene therapy and gene engineering is that it can lead to unknown side effects such as allergic reactions and toxicity. Genes which weren’t naturally there, and are artificially added can affect humans, animals or the patient/plant itself in negative ways. In conclusion and to put simply, evolution is the way that living things including fauna and flora change over time. Evolution is an on going process that first began around 3.5 billion years ago according to scientists, and we are still learning new things about evolution and the function of natural selection, genetic drift, mutations and gene flow. Evolution occurs naturally when the environment changes and when mankind interferes with this process we don’t completely know what the outcomes or side effects could be, this could interfere with all living thing. Gene therapy and gene engineering are both good examples of how tampering with evolution can have positive and negative outcomes.
