Evolution
Adaptation
The way something gradually develops and makes

changes over time.

The way something changes for the better to suit something new or different.

He discovered that humans and apes shared ancestors which led to this famous image…

How Evolution Works
The

thing about evolution is that it happens over the space of a long, long, long time so we don’t really notice it happening.

One animal, plant or person doesn’t
just change… there are small
changes with each new generation.

to not only survive but to survive better. Some of

these changes are down to habitats.

Darwin studied different finches living in different parts of the Galapagos Islands and realised, even though they were different, they all had the same ancestors!
Some had evolved to have larger beaks in certain areas, some with smaller beaks in other areas due to different food being available.

of a few generations start to make noticeable differences.
Looking at

the Galapagos finches

The ones with large beaks reproduced and had offspring.

More of these offspring inherited large beaks and survived.

In other parts of the Galapagos, smaller beaks ensured better survival than larger ones.

The adaptations meant that over a long period of time, the Galapagos finches evolved adaptive traits that caused differences between them.

slightly different from the last but different families make their

own generational changes and this can lead to species going down different evolutional paths.

This is part of the tree of life that shows how birds, reptiles and even humans developed from fish… but remember… over millions of years!
