Identify early ideas about evolution?
Setler79 [48]

Explanation:

Naturalists began to focus on the variability of species; the emergence of paleontology with the concept of extinction further undermined static views of nature. In the early 19th century Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution.

In classical Latin, though, evolution had first denoted the unrolling of a scroll, and by the early 17th century, the English word evolution was often applied to 'the process of unrolling, opening out, or revealing'. It is this aspect of its application which may have been behind Darwin's reluctance to use the term.

The genotype is the combination of alleles an individual has.

The karyotype is an individual's collection of chromosomes, paired and ordered.

A homozygote individual has the same alleles for a particular gene.

Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to
maw [93]

The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.

<h3><u>Explanation</u>:</h3>

Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.

This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
