The consolidation of Biological, Cultural and Technological Evolution has majorly determined and advanced how we (Homo Sapiens) have evolved and how we live our lives today.
Biological Evolution
Biological Evolution refers to changes in the human population that is caused from natural selection acting over generation on inherited phenotypes and production under a particular set of environmental conditions.
Biological Evolution can be identified throughout Hominjn Evolution by their physical traits, such as body size and shape, blood type and variation of skin;amount of hair and/or pigment that has adapted to the specie's environmental condition.
The 'Out-of-Africa' theory suggests that modern human exist because of prehistoric migration that resulted in inherited variation increasing over about 200,000 years.
Cultural Evoltion
Cultural Evolution is the change in humans societies over time, where those changes are socially conveyed (not genetically inherited). This also refers to a variety of learned behaviours.
Cultural Evolution has been established during Hominin Evolution through tools, learning social rules, learning a musical instrument, skills, imitation, teaching, customs, knowledge, new ideas, transport, food production, medical treatment, fashion, ART, symbols and communication. Over time, cultural evolution progressed as more knowledge and ideas are passed down over time through 'collective learning', from generation to generation, specie to specie. Cultural Evolution can be transmitted through the use of: speaking, writting/drawing and signed language.
Evidence of a flute made from a bone of a bird (seen in figure 1) compared to a modern flute (figure 2) expresses that new ideas and knowledge were learnt from others to gradually enhance it.

Other documentation of Cultural Evolution is recognised through the upgrading of stone axes and skills with fire; source of energy used for nuclear power.
Technological Evolution
Refers to change in technology over time that gives a specie increased control over their material environment.
Technological evolution such as: tools, machines, automatons (self-controlled machines) and medical procedures are used to abrogate and go beyond physical limitations and extend capabilities of a species senses.
This has lead to inventions of steam power to electric power, space travel, laser, fibre-optics, mobile phones, cars, planes, treatments and/or cure for illnesses.
Cultural vs Technological Evolution
The Technological Evolution has increased and worked in conjunction with cultural evolution. The development of phones and internet (Technological Evolution) allows communication to anyone at anytime, disregarding distance barriers. Sharing new ideas and building on intelligence over many species (Cultural Evolution) has generated the advancement of today's Technology.
Biological vs Technology Evolution
Evolved Technology such as medical interventions; machines that detect and modify DNA, diseases and/or conditions. Therefore have given the ability to manipulate Biological Evolution.
Biological vs Cultural Evolution
Imitated skills changed they way a specie adapted and controlled their environmental conditions. For example the use of fire was learnt from other ancestors (Cultural Evolution) which changed the way the species lived. They had power over their predators and had the capability to migrate. This increased variation in the population, altering the Biological Evolution.
Medical Intervention
Intervening evolution by using medicine to change the survival of an organism, despite the selection pressures.
Medical intervention has recently reduced due to increased technological evolution, giving the accessibility to perform medical intervention. It has altered the way species live and how long they live for, it is able to moderately control gene and all over biological evolution. Through cultural evolution, it has and will continue to develop rapidly.
