About me

Hi, I’m Aidan a Biology student at Durham University.

My experience

Having regularly tutored a brother with learning difficulties, I have developed the patience to understand and help people of all abilities. Mentoring younger pupils at school and having multiple years teaching experience in the army cadet force, allows me to develop a relationship which improves not only academics but overall organisational and working attitudes to life. I have an outgoing personality able to engage and bring the best out of all my students. 

What do I teach?

At GCSE I scored 100% in both Biology and Geography amongst 8A*s and 3As before completing 4 A-levels. I would love to help you by creating personal lesson plans for your syllabus, covering the topics you want, at a pace you decide.

My lessons

Knowing full well how it easy it is for teenagers to lose focus in the classroom, I prepare varied and creative lessons to ensure you are always learning. Nevertheless I understand exam success is only achieved through great technique developed with access to resources such as past papers, examiner feedback and specifications which I support all my students with.

Get in touch

Please feel free to message me, I would love to hear how I can help you. Before we start we can even arrange a free meet the tutor session!

I have improved my exam technique. I have required more deep thinking.

Questions Aidan has answered

Explain the formation of a new species

Speciation (the formation of a new species) can be broken down into a few concise steps.

The most important step is the isolation of two populations. This usually occurs because of physical factors such as a lake drying up and being separated into two smaller lakes.

As a result the fish in each lake are no longer able to breed with the fish in the other lake, resulting in no alleles being transferred between the populations.

Within each population mutations (random changes in the base sequence of DNA) will occur. But importantly since the changes are random the mutations that occur in each population will be different.

Similarly since both populations are now in different environments, physical characteristics of each enviroment such as water temperature will vary. As a result a mutation which may be favourable to cooler water conditions such as a thicker fat layer, may be favourable to one population of fish but detrimental to the other where the water is warmer.

As a result of differing selection pressures due to the differences in physical conditions(example above), both populations will evolve in separate directions to favour their new environment. This will lead to greater and greater genetic differences between the populations over time as a result of changing allele frequencies.

Eventually both populations even if no longer physically isolated will be reproductively isolated. Reproductive isolation is where both populations are no longer able to interbreed to produce fertile offspring, a requirement for an individual species.

Reproductive isolation can occur due to factors such as incompatible genitalia and non overlapping mating seasons. But importantly when two populations can no longer reproduce to produce fertile offspring they are considered two separate species.
