For example, they will evolve and improve the shape of their tools over time, and will fashion left handed or right handed tools. These tools are usually made to help catch insects and other invertebrates.

The discovery puts back by 10 million years the colonisation of land by plants, and suggests that a diversity of land plants had evolved by 472 million years ago.

Many people in the UK are unable to identify the location of their major organs, a study suggests. A team at King's College London found public understanding of basic anatomy has not improved since a similar survey was conducted 40 years ago. Less than 50% of the more than 700 people surveyed could correctly place the heart, BMC Family Practice says. Under one-third could place the lungs in their
