Document Summary
Castor canadensis capital in first word, lower case in second word. Convergent evolution, violet in ontario vs. darwin orchid. Converged on the same appearance with nectar spur. Lizard adaptatio(cid:374)s: puffs up a(cid:374)d shoots (cid:271)lood out of it"s eye: avoiding the heat by going underground, others might adapt towards tolerating rather than avoiding. This is an evolutionary strategies: change in the population as a whole: wood frogs literally freeze in the winter and then come back to life wtf, orga(cid:374)is(cid:373)s do (cid:374)ot adapt, it"s the populatio(cid:374)s that adapt. Observation prediction experiment: cactus in california and similar plant in south africa are an example of convergent evolution. Larger circles have smaller surface area to volume ratios: the more surface area you have, the more water is lost in plants. This explains the shape of cacti being large in order to prevent over heating.
