Homo neanderthalensis (in northern areas, dealt with harsh winters) Natural selection:in all living populations, in each generation there are individuals that survive and reproduce and those that do not, and the next generation is like those that succeeded to reproduce. Natural selection:in all living populations, in each generation there are individuals that. Oparen & haldane - random chemical reactions: small organic molecules produced, molecules became polymerized (chains created, replicator molecules - rna (ribonucleic acid), dna (deoxyribonucleic acid) Plant pathogen - infects plants, death or stunting.
