you own answer please 1. Why do you think organism needs to evolved? 2. What are the major differences of man now form before? 3. Why do we need to know where we came from?
1. First of all, it is not really organisms that evolve: they undergo mutations during their lifetime that may be transmitted to their offspring, and over time, change the characteristics of the population.
The main explanation for why evolution occurs, is that without the variety it introduces between individual organisms of a population, the species is very likely doomed for extinction. The environment may seem stable, but over linger timescales it is an ever-changing backdrop, that poses new challenges to successive generations. Continental drift, volcanic eruptions and meteorites can effect climate change, so in the long run, nothing stays the same. So organisms that create perfect copies of themselves are vulnerable to extinction. And if there ever were populations of such organisms, they have lost out in the struggle for their continued existence.
Only populations in which the organisms made errors in copying their genetic information contained within their resulting variety those lucky few who could cope with the changed environment they encountered, and in which their forebears would have been hopelessly lost. There was no foresight, no planning, only happenstance. This is why species should be expected to evolve over time.
In short: evolution inevitably evolves evolvability
3.It gives you a sense of identity
Learning about your ancestors, celebrating family traditions, embracing your culture, and understanding where you came from can open your eyes to how beautiful and unique you are. It can also give your sense of self-worth and belonging a boost.
