CER RESPONSE: Simplest animals, like sponges reproduce asexually, based on this info why are jellyfish considered more complex yet still not as complex as a mammal?

This may be a stretch but. Some species of jellyfish don’t reproduce exactly. For example the Medusa of turritopsis dohrnii is known as immortal they don’t die form old age atleast but when they reach a certain stage in their life they can turn back into their polyp state but this process requires certain cell types.

The Medusa’s reproduction goes like this:

Planula larva - Polyp - budding polyp - ephyra - Medusa(adult) - planula larva (the cycle repeats)

Hope this was right or atleast helped :)

Oi oi oi oi oi oi  i think it is true

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
