Hello Science Fans!
To conclude our series on evolution, we look at the minute changes happening within our cells that *could* eventually result to evolution. It’s a combination of accidents and environmental change that facilitates “survival of the fittest”.
Here we have an overview of the DNA, the awesome molecule known as the blueprint of life. But beyond that, we also talk about all the different kinds of mutations that can either:
Get corrected by the cell
Cause a cell to die (by apoptosis)
Make us sick
Or be the root of evolution
But please take NOTE!
Mutations happen spontaneously and randomly. There is no rhyme and reason behind them. At least to the extent of how they can cause beneficial or harmful changes to the body. There may be more that we discover about mutations along the way, so this thought is limited by the science I have read and understood to this day.
But evolution only eventually proceeds, when enough mutations are passed on from one generation to the next, and that these mutations actually lend the organisms competitive advantage in the event of an environmental change!
Of course, all that we understand about evolution now has been verified through genetic technology, but the study of evolution is ancient! So how did scientists study evolution prior to our full understanding of the DNA?
Well, they looked at biological structures, of course!
