According to the theory of today and acirc and 128 and 153s organisms evolved from past organisms.?

That's correct! The theory of evolution states that organisms have evolved over time from common ancestors through the process of natural selection. This gradual change in species over generations is driven by factors such as genetic variation and environmental pressures.


Sexual reproduction evolved before the evolution of?

Sexual reproduction evolved before the evolution of multicellularity. Organisms were able to reproduce sexually as single-celled organisms before multicellular life forms emerged.


Colonial organisms probably evolved into what?

Colonial organisms likely evolved into multicellular organisms through a process known as cellular differentiation, where specialized cells with specific functions developed within the colony. This evolutionary transition allowed for increased complexity and efficiency in tasks such as reproduction, growth, and survival.


Which kingdom did organisms evolve first?

Organisms first evolved in the kingdom Bacteria. Bacteria are single-celled organisms that lack a nucleus and other organelles. They are considered the earliest and most primitive form of life on Earth.


The first eukaryotic organisms on earth were?

The first eukaryotic organisms on earth were likely single-celled organisms such as protists, which are a diverse group of organisms that have a nucleus and other membrane-bound organelles. These organisms are thought to have evolved around 1.6-2.1 billion years ago.

What According to the theory of today's organisms evolved from past organisms?

No, that isn't a statement made about evolution. The theory of evolution concerns how organisms have changed over periods of time. Everything has to have come from something! However, all living organisms alive today have evolved from predecessors, or have not really evolved much at all, e.g. Gingko bilboa and several species of sea animals.
