Speciation and variation – Evidence of common descent

As predicted by evolutionary theory, populations evolve in response to their surroundings. In any ecosystem there are finite opportunities to make a living. Organisms either have the genetic tools to take advantage of those opportunities or they do not. House sparrows arrived in North America from Europe in 1800s. Since then, genetic variation within the…

Should I Boycott the Election? #GE2015

To vote, or not to vote, that is the question. Whether ’tis Nobler in the mind to suffer The Slings and Arrows of outrageous Policies, Or to take Arms against a Sea of empty words, And by opposing, end them? I’ve just been having a long argument with someone who is “boycotting” the UK election…

Jealousy and Propriety in Monogamous Relationships

Many polyamorous people were serial monogamists beforehand and perhaps due to a situation where they’ve had to chose between 2 people whom they love equally, have come to the conclusion that monogamy encourages emotional hurt and exacerbates rather than abates destructive forms of jealousy and a toxic sense of propriety. Many eschew the Judeo-Christian definition…

Human Chromosome 2 – Evidence of Common Descent

Since the mid-1800s, biologists have generally shared the belief that all living things descended from a single common ancestor. Based on fossil evidence and comparative anatomy, Charles Darwin proposed that humans and great apes, which including chimpanzees, gorillas, and orangutans, share a common ancestor that lived several million years ago. More recent research has propped…

Artificial Selection – Evidence of Common Descent

Artificial selection is not direct evidence of evolution, but it is indirect evidence, a process that helps us to understand natural selection. Humans have been artificially selecting and domesticating animals and plants for many thousands of years. In effect, domestication is a long-term, practical experiment that clearly demonstrates that species can actually change dramatically by breeding…

Polyamory – What is it?

Polyamory is a relationship style that involves an openness to being involved with more than one person at the same time rather than accepting social norms that dictate monogamy as the only acceptable form of love. The word “polyamory” means “loving more than one”. I have been learning a lot about this interesting relationship style…
