Population genetics

Darwin’s Origin of Species still provides the best single account of evolution, but modern discoveries allow us to fill in some details and make some additions. Learn about some of these here!

Sex and evolution

What role does sexual reproduction play in evolution? In this article, we will consider how recombination and genetic variation drive evolution.

Adaptation

Darwin’s theory of evolution by natural selection states that the adaptations of an organism to its environment arise because of the greater chance of survival of those offspring that have a favourable variation caused by random mutation, which they then pass on to their offspring.

Evolution: Making sense of life

“Nothing in biology makes sense except in the light of evolution.” This was famously said by Theodore Dhobzhansky, one of the most eminent biologists of the 20th century, and practically every biologist in the world agrees with him. But what does such a sweeping claim mean?

Did volcanoes kill the dinosaurs?

Scroll to the bottom of the page for today’s task! It’s the age-old question – how did the dinosaurs die out? What if volcanic activity was responsible for their extinction? And are we heading for another mass extinction today? Step back 66 million years and try to uncover the answers to these questions and the…

Evolution, ecology and volcanoes

There are many questions one can ask that link evolution and ecology to volcanoes… Let’s start at a small scale in both space and time. Are plants and animals growing on and near active volcanoes different from those growing elsewhere? Yes, they are! Volcanic soils are rich in certain minerals, and plants like coffee grow…
