What else can I help you with?
What happened to life-forms when the ozone layer formed in the upper atmosphere?
When the ozone layer is formed, the life forms evolved. They were not possible earlier.
Complex forms of life evolved over long periods of time from simpler forms?
According to the theories of Charles Darwin complex forms of life evolved over long periods of time from simpler forms.
The most successful forms of life that have ever evolved are the?
vertebrates
What life forms evolved during the Permian period?
gymnosperms
What is The earliest life forms on earth lived?
The earliest ones still around are stromatolites, but there were lots of earlier life forms.
Are most adult protists diploid or haploid?
Most adult protists are diploid, meaning they have two sets of chromosomes. This is in contrast to some lower life forms, such as algae, which can have a haploid dominant life cycle stage.
A series of fossils shows how mammals evolved from what?
Less complex life forms.
Which scientist believed that life had a common beginning with new forms branching off from earlier forms?
Charles Darwin
What trait or traits unifies all the members of the protists with all other life forms?
All protists share the trait of being eukaryotic, meaning their cells contain a nucleus and other membrane-bound organelles, which unifies them with all other life forms that are also classified as eukaryotes. Additionally, protists exhibit diverse modes of nutrition, including photosynthesis, ingestion, and absorption, similar to other life forms that employ various strategies for energy acquisition. This cellular complexity and metabolic diversity highlight the shared evolutionary lineage of protists with plants, animals, fungi, and other eukaryotic organisms.
Where on Earth did the first life forms evolve?
The first life forms are believed to have evolved in the oceans around 3.5 billion years ago. This early life consisted of single-celled microorganisms like bacteria and archaea. These organisms evolved and diversified over time, eventually giving rise to more complex life forms.
Did humans evolve from a star?
No. Humans are not made from stars. However, every element in the human body except hydrogen and perhaps lithium came from an exploding star. The human body contains carbon, nitrogen, oxygen, iron, chlorine, sulphur, and a number of other elements, all made in stars. All became available for other uses when the stars exploded.
Why life evolved?
to exchange energy and mass through controlled biochemical timebound forms and structures.
