Early life on Earth consisted of single-celled organisms that reproduced by dividing into half or what is formally known as asexual reproduction. As life evolved and more complex and multi-cellular organisms were created, two sexes became distinguished- the male and the female, which were both required in the process of sexual reproduction. It is believed that nature promotes sexual reproduction since it provides an opportunity of recombination of genetic material in a given population.
There is evidence for sexual production in plants as well and distinct male and female plants do exist. Usually a female produces an egg which is then fertilized by a male gamete to give rise to an embryo, which grows into an adult organism. So, when we were busy considering ‘Dioecy’ (species have distinct male and female organisms) as one proof of our evolution, scientists have found that certain females can reproduce without the need of a male. Offspring produced in such a manner are often females a…
