Discuss the diversity of secuality in the living organisms
Answers
Answer:
The first living organisms simply replicated themselves like carbon copies. It was easy and it was fast. Until 1.3 billion years ago, when something new happened.
Sex!
Some organisms first needed to find a mate in order to reproduce. It was slow, because not all progeny were female, which slowed the process down. So, why the change? Why did this new idea survive and become so successful? What were the benefits over a fast copying system that could populate more quickly?
Sexual reproduction meant that an organism could combine half of its genes with half of another’s genes, which creates new combinations for each generation. Though slower, sexual reproduction results in offspring that can do more than its parents.
Shuffling and recombining genes creates complexity, but also more ways to survive a changing world. Nature is not static. If you can mix genes, there’s a better chance your offspring will survive. Sexual reproduction started becoming successful because organisms began to design more ways to find food, manage pathogens, and attract the best mate. Genetic diversity meant that a species could change over successive generations.
If a design never changes, it may not be able to adapt to new conditions. Complexity, and even mutations that don’t work presently, are like having extra ideas in your back pocket. They might not fit the old system, but when the system changes–voila!
There are still organisms today that can reproduce by themselves (asexually) like some bacteria, plants, worms, and even some lizards and snakes. This resistance may become a dead end if faced with surviving the fast changes the planet is now experiencing. Life succeeds best when it’s adaptable.
For example, if a flower is tied to a specific pollinator that disappears, that flower might go extinct. Living in such a specific niche might be very successful…but only until things change. Whereas, if you have a wider variety of genes in your DNA, the possibilities and variations of design are endless.
Explanation:
Diversity means having a range of people with various racial, ethnic, socioeconomic, and cultural backgrounds and various lifestyles, experience, and interests. Diversity should encompass various backgrounds and perspectives including: ethnicity, race, geography, political belief, sexual orientation, etc.
