→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.
The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.
And how would that ↑ explain Evolution?
Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.
→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.
Hope it helped,

Answer:
protons its the flow of electricity but does not controll it
D. Polar regions receive less solar energy and heat per unit area than tropical regions
Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.
Answer:it's evidence of rapid cooling
And small crystals and rapid cooling
Explanation:
<h2>The Thalamus.</h2>
Explanation:
Dencephalon is the part of the forebrain and includes three parts- epithalamus,thalamus and the hypothalamus.
Epithalamus is a non-nervous part , it remains fused with pia mater and forms the anterior choroid plexus.
The thalamus is located between the midbrain and the cerebral cortex. It filters sensory information and directs them to appropriate parts of cerebrum.
Hypothalamus is located beneath the thalamus. It is an integrating center for many important homeostatic functions.
