I would very much appreciate your help on how to understand the
dynamics of this system of differential equations.

RNA can be heredity molecule
Findings in mice suggest RNA found in human sperm might also affect human
inheritance

Explaining the evolution of cooperation is one of the trickiest problems in
evolutionary biology. Modelling interactions using game theory has yielded
dividends, but this approach is often limited by a small set of possible

When we have a well adapted organism and put it in a different
environment. And this new environment is the same as the old one, only
the temperature is 5 degrees higher. Then the Baldwin effect goes
something like this (i dont know biology):

I read somewhere that living creatures could  have long-chain molecules
with the helix either left or right handed, but all on this planet are
twisted the same way. And this suggested that life began from a single
starting point. If life began, say in ten different places, then the

Forcing Darwin's hand: capturing natural selection in a flask
Even with modern genomic tools, it's a daunting task to find a smoking gun
for Darwinian evolution. The problem lies in being able to say not just when

The chloroplasts in green plants are descended from cyanobacteria.
I recently read something that said that rhodophyta also use
endosymbiotic cyanobacteria; apparently the red pigments are
"extra".

Genetic evidence for complex speciation of humans and chimpanzees

Which is correctest: Evolvability or Evolubility? I've seen the first
used by Richard Dawkins, but not the second. However, the word is
young, and the second is in keeping with the morphological rules thus
far. What say we?
