Where the first man came from according to science?
he evolved from a monkey No, he evolved from an ape.
Where do scientists believe plants evolved?
They believed plants evolved from prehistoric times.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
Mitochondria evolved from aerobic bacteria.Chloroplast evolved from photosynthetic bacteria.
Does a snake have an open circulatory system?
no they dont. They have a closed circulatory system because they are so long.
Why were changed in the respiratory and circulatory systems so important to vertebrate evolution?
they improved oxygenation of tissues
What would happen if humans evolved without blood?
Humans are primates. Long before any species of primate evolved a replacement for the mammalian circulatory system, they would probably no longer be considered mammals. Actually, virtually all vertebrates possess a similar circulatory system. I think some invertebrates may get along without blood.
What would have happened if humans had not developed a circulatory system?
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Are small amounts of carbohydrates needed for good health?
It is better with large amounts of carbohydrates. That is what our digestive system has evolved to digest. Complex carbohydrates and not simple sugars.
What does a cat's anatomy look like?
A cat has the same muscles, organs and basic bone structure like most other animals: Cats have short limbs and strong muscles for pouncing and sprinting, the circulatory and digestive system works just like other mammals', although a cat's intestinal tract is shorter than omnivores and herbivores as a cat has evolved to be very efficient at digesting meat.

Why are red blood cells built to carry oxygen?
Something has to do this job, so if it wasn't red blood cells then it'd need to be something else. Unless, of course, mammals had evolved in some other way which did not have a circulatory system.
Two basic types of circulatory systems that have evolved over time?
open and closed circulatory systems.open system: the blood leaves the discrete vessels and bathes at least some non-vascular tissues directly. (crustaceans, mollusks, arthropods, etc.)closed system: there is always at least a thin vessel wall separating the blood from the other tissues. (mammals,birds, etc.)
Who invented horses?
The horse evolved over the course of 65 million years. They changed from leaf browsing four toed fox sized equids into taller single toed grass grazers with a mono gastric digestive system. There is scientific proof that shows how the horse has evolved over the years. They were not 'invented' by anyone.

What did electric guitars evolved from?
they evolved from the acoustic guitar which evolved from the lute which evolved from the harp i believe.
