Fitness and Selection

Absolute Fitness vs. Relative Fitness

Absolute Fitness refers to how many offspring an organism has over it's lifetime. 



Relative Fitness is the comparison of how many offspring and organism has over it's lifetime compared the most successful organism in the population regarding reproduction.



Population Through Positive Selection:

Two Evi's have different color patterns, the blue Evi blends into their environment better due to a recent change in sunlight, it is dark 90% of the time now. Due to the the blue camouflaging better Evi's have a better chance of survival, leaving them to reproduce the most off spring, this leaves the most beneficial alleles to be passed down (in this case the coding for a blue color). This process is called positive selection.

    This is a great visual representation of positive selection, your characters are super cute and thoughtfully drawn out!

Natural Selection

 Survival of the "Good Enough" vs Survival of the Fittest         Natural selection is depicted as survival of the fittest, however, this implies that only the fastest, strongest, and most superior reproductive systems will carry on their genes/survive. For example in this boxing match Mr. "Fittest" would always win, this is not the case in natural selection. The term "fittest" can be misleading and depict bad odds for the "good enough" organisms.      The "good enough" organism just has to be better than the organisms around them and survive long enough to reproduce. For example if a tiger were to chase after these organisms the good enough organisms just has to out run another organism or hide better than another organism. See picture below. Mr. "Good Enough" survived and survived many for occasion identical to this one and was able to reproduce and pass on his "good enough" genes.

The Big Issues- Trends in Evolution

Image
     Today the topic is "Trends in Evolution." What are the parameters for a trend? Are there trends in evolution? Are there evolutionary trends across lineages? Is evolution progressive? Let's dive in!      A trend cannot be a random occasion, for example if it is 110 degrees out for one day when it is usually 70 degrees that time of year; if the heat continues for a period of years continuing in an upward direction, this could be considered a global warming trend. Trends for to be a trend in one direction or another.      Now that we have covered what a trend is, how is it applicable to evolution? Trends are not seen in evolution across all linages, for example size of organisms. It seems that a lot of species have grown bigger, but this is not the case across all linages, some sizes have decreased, so we cannot say there is one evolutionary trend across all linages. However, there are specific linages that show evolutionary trends. For exa...
