What else can I help you with?
How long ago did bacteria and archaebacteria diverge from a common ancestor?
It is believed by many that the archaea and bacteria developed separately from a common ancestor nearly 4 billion years ago.
What is the mating of two closely related individuals?
Organisms sharing a common ancestor are of common descent. The LUA , the last universal ancestor, lived 3.9 billion years ago.
Is the following true or false The ancestor of all eukaryotic cells evolved about 2 billion years ago?
True. The ancestor of all eukaryotic cells is thought to have evolved approximately 2 billion years ago through a process of endosymbiosis, where prokaryotic cells engulfed other prokaryotic cells, leading to the formation of more complex eukaryotic cells.
What are species that share a very distant common ancestor?
An example of species that share a very distant common ancestor are humans and yeast. Despite belonging to different kingdoms (Animalia and Fungi), they share a common ancestor that existed over a billion years ago. This distant relationship underscores the vast diversity of life on Earth.
Do humans and bats have a common ancestor?
Yes, humans and bats share a common ancestor. Both humans and bats belong to the group of mammals, which evolved from a common ancestor millions of years ago.
Is it true that the ancestor of all eukaryotic cells evolved about 2 billion years ago?
yes and no
Therefore most biologists assume that all living things had a common single celled ancestor 3.5 billion years ago.?
Most biologists believe that all living organisms share a common ancestor due to the similarities in genetic material, cellular structures, and metabolic processes observed across diverse life forms. This common single-celled ancestor, which is thought to have existed around 3.5 billion years ago, likely gave rise to the vast diversity of life we see today through processes such as evolution and natural selection. This foundational concept is supported by extensive evidence from genetics, paleontology, and comparative biology.
What organisms share the most recent common ancestor?
Organisms that share the most recent common ancestor are those that are closely related in evolutionary terms, such as humans and chimpanzees. They both belong to the family Hominidae and diverged from a common ancestor about 6 to 7 million years ago. Other examples include all mammals, which share a common ancestor that lived around 200 million years ago. The concept of a common ancestor highlights the interconnectedness of life through evolutionary processes.
When is the common ancestor of humans and chimps thought to have lived?
It's thought to be about 5 to 7 million years since humans and chimps shared a common ancestor.
That crocodiles share a common ancestor with bird dolphins and dog support your answer?
Crocodiles and birds share a common ancestor. This can be seen by comparing the internal anatomy of the two. Dogs and Dolphins also have a common ancestor. Their skeletons again are both distinctly mammillian. The ancestor of dogs and dolphins and the ancestor of birds and crocodiles will again share a common ancestor, but you will need to go much further back. I am not sure of the timescales but we are talking tens to hundreds of million years.
How long ago did birds and humans share a common ancestor?
300 million years.
What is the original ancestor that the plant-animal descended from?
Plants and animals share a common ancestor that was likely a unicellular, photosynthetic organism similar to modern-day green algae. This ancestor existed over a billion years ago, during the early evolution of eukaryotes. Through a process called endosymbiosis, some of these organisms developed the ability to perform photosynthesis, leading to the evolution of plants, while others evolved into various animal forms. Thus, the divergence between plants and animals began from this ancient common ancestor.
