The Guppy Game: Understanding the big ideas of natural and sexual selection
2012
The Science Teacher
Preserved Fulltext
They represent aspects of two of the big ideas in science: evolution and natural selection (NRC 2011). To help students understand these ideas, we developed the "Guppy Game." ...
In this article, we describe the game and how we used it in an AP biology classroom to model the dynamic processes of population genetics and environmental influence on behaviors. ...

Using this machinery, we study the role of mutation in changing environments in the presence of sexual reproduction. ...
Finally, we also show that in static environments, sexual evolution with mutation converges, for any level of mutation. ...
In contrast, under sexual evolution with mutation the probability of long term survival is strictly positive. ...

We then turn to the possible impact of grandparental acts of altruism, and examine whether benefits of grandparental care in industrialized societies may manifest in terms of less tangible dimensions, ...
Although grandparents in industrialized societies continue to invest substantial amounts of time and money in their grandchildren, we find a paucity of studies investigating the influence that this investment ...
Whereas evolutionary theorists may define parental investment as all the resources that parents invest in children to maximize their chance of survival to sexual maturity, it is well known that parents ...
